How can I do this?

Hi, I hope you are doing well in this pandemic. I am new in matlab, and I would like to know how do I develop a script that exemplifies the use of a certain function. If you could give me an example of any function I would appreciate it. Thanks

[Jan]

The question is not clear. Would this script solve the problem?

My program is like that:

function [ST] = add_patient(ST)

tempname = input ('Enter the name of the patient you want to add: ','s');

newPID= ['P',num2str(str2double(ST(end). Patient_ID(2:end))+1,'%08.f')];

newSNS= input('Enter the patient's NHS number: ');

while length (newSNS)~=9 %SNS_Numbers Size Check

warning('Invalid number, number must be 9 digits long')

newSNS= input('Enter the patient's NHS number: ');

end

newBirthday = input('Enter the patient's date of birth(MM/DD/AAAA): ','s');

[newBirthday] = date_check(newBirthday);%Function that checks for impossibilities in dates

reply = input(['Is this your date? ',newBirthday,' Nota: Form is MM/DD/AAAA\n Yes(1)/No(2): '],'s');

if isempty(reply) %Checking if the date is correct

reply = 1;

end

while reply == 2

newBirthday = input('Enter the patient's date of birth: ','s');

[newBirthday] = date_check(newBirthday);

reply = input(['Is this your date? ',newBirthday,' Nota: Form is MM/DD/AAAA\n Sim(1)/Não(2): '],'s');

if isempty(reply)

reply = 1;

end

end

newWeight = input('Enter the patient's weight(kg): ');

newHeight = input('Introduction to patient height(m): ');

boolnH = newHeight;

while boolnH > 10 %Warning for if the height is greater than 10 meters (Probable lack of '.')

warning(['You entered as height, in meters, ',num2str(newHeight),'. Do you want to proceed?'])

reply = input ('Yes(1)/No(2): ','s');

if isempty(reply)

reply = 1;

end

if reply == 2

newHeight = input('Introduction to patient height(m): ');

boolnH = newHeight;

else

boolnH = 1;

end

end

newCOPD = input('the patient has POTD?. Yes(1)/No(2)','s');

if isempty(newCOPD)

newCOPD = 1;

end

if newCOPD == 2

newCOPD = 'No';

elseif newCOPD == 1

newCOPD = 'Yes';

end

ST (end+1) = struct('Patient_ID',newPID,'SNS_Number',newSNS,'Name',tempname,'Birthday',newBirthday,'Weight_kg',newWeight,'Height_m',newHeight,'COPD',newCOPD,'CTR','-');

end

I have an excel file with patient data (weight, height, illnesses, etc). This function adds a new patient with new data. Now I to create a new script that exemplifies the use of this function.

Thanks for helping

So the input argument is the table from the excel file. So this might work if the excel file is in the same folder as the function and this script:

file = 'filename'; % Use the name of the excel file, and omit the extention.
table = table2struct(readtable(file)); % The script updates a struct, so read in the excel file as a table and convert to a struct.
table = add_patient(table); % Run the function on the struct and update the table.
writetable(table,file); % Overwrite the excel file.

Thank you for your help. It worked.

One last question if you can help me. In the same excel file(Sheet1 and Sheet2). How can I show the most recent exam to the user of a given patient. For example using the read_last_exam() function. Thanks again

[Scott Satinover]

You need to retrieve the results for a given patient, and the results are found on the second tab. First, pull the results from the spreadsheet on the second tab using the name-value argument the specifies the sheet you want to retrieve, using the Sheet name-value argument. Without this argument, the readtable function only reads the first sheet, so you need to specify it here:

file = "Data";
exams = readtable(file,Sheet=2);

The readtable function returns most text in cells as part of a cell array, which you can't sort or filter data with. But the data you want to retrieve is based on data that is a cell array. To work around this, convert the PatientID column into a string array with the string function:

exams.PatientID = string(exams.PatientID);

Now, filter your results and create a new table. Specify the patient ID as a string, and then use logical expressions to filter your results. For example, if you want to look up the records for P00000008, enter this:

ID = "P00000008";
filtered_exams = exams(exams.PatientID == ID);

Then, to return the latest entry, use index notation on the filtered table:

filtered_exams(end,:)

To learn more about this functionality, go through the MATLAB Onramp and MATLAB Fundamentals training.

I recommend you take a look at this category:

If you want a more interactive learning experience, take a look at the MATLAB onramp tutorial:

It's super helpful for learning the basics of MATLAB.

This program was provided to me. The program is like that:

function [ST] = add_patient(ST)

tempname = input ('Enter the name of the patient you want to add: ','s');

newPID= ['P',num2str(str2double(ST(end). Patient_ID(2:end))+1,'%08.f')];

newSNS= input('Enter the patient's NHS number: ');

while length (newSNS)~=9 %SNS_Numbers Size Check

warning('Invalid number, number must be 9 digits long')

newSNS= input('Enter the patient's NHS number: ');

end

newBirthday = input('Enter the patient's date of birth(MM/DD/AAAA): ','s');

[newBirthday] = date_check(newBirthday);%Function that checks for impossibilities in dates

reply = input(['Is this your date? ',newBirthday,' Nota: Form is MM/DD/AAAA\n Yes(1)/No(2): '],'s');

if isempty(reply) %Checking if the date is correct

reply = 1;

end

while reply == 2

newBirthday = input('Enter the patient's date of birth: ','s');

[newBirthday] = date_check(newBirthday);

reply = input(['Is this your date? ',newBirthday,' Nota: Form is MM/DD/AAAA\n Sim(1)/Não(2): '],'s');

if isempty(reply)

reply = 1;

end

end

newWeight = input('Enter the patient's weight(kg): ');

newHeight = input('Introduction to patient height(m): ');

boolnH = newHeight;

while boolnH > 10 %Warning for if the height is greater than 10 meters (Probable lack of '.')

warning(['You entered as height, in meters, ',num2str(newHeight),'. Do you want to proceed?'])

reply = input ('Yes(1)/No(2): ','s');

if isempty(reply)

reply = 1;

end

if reply == 2

newHeight = input('Introduction to patient height(m): ');

boolnH = newHeight;

else

boolnH = 1;

end

end

newCOPD = input('the patient has POTD?. Yes(1)/No(2)','s');

if isempty(newCOPD)

newCOPD = 1;

end

if newCOPD == 2

newCOPD = 'No';

elseif newCOPD == 1

newCOPD = 'Yes';

end

ST (end+1) = struct('Patient_ID',newPID,'SNS_Number',newSNS,'Name',tempname,'Birthday',newBirthday,'Weight_kg',newWeight,'Height_m',newHeight,'COPD',newCOPD,'CTR','-');

end
