How to solve: Error using "csvread". Too many output arguments

I want to read 40 .csv files. In every csv file there are 251 rows and 4 columns. it is showing error:

Error using csvread

Too many output arguments.

Error in readingALLcsvFILES (line 8)

[num,txt,raw{k}] = csvread(myfilename); %reading the execel file

This is my code:

clear all

numfiles = input('Enter no. of files');     %entering no. of files to be calculated
mydata = cell(1, numfiles);                %creating a cell array for all the files

for k = 1:numfiles                                      %begin of loop for each file calculation
  myfilename = sprintf('DAT0000%d.csv', k-1);             %calling the excel file 
  [num,txt,raw{k}] = csvread(myfilename);               %reading the execel file
  n{k}=raw{k}(1,1);                  % Giving weld time in a cell array of 1x1
    n{k}=cell2mat(n{k});             % converting n into a matrix value
DCRfile{k} = raw{k}(2:(n{k}+1),:);   % creating a cell array for DCR with time, cuurent and voltage value
DCRfile{k}(:,2)=[];                  % deleting 2nd column with value '*'
DCRfile{k}=string(DCRfile{k});       % convering DCR cell array to ta string array

DCRfile{k}(:,1)=erase(DCRfile{k}(:,1),'ms');   % erasing units in DCR string array
DCRfile{k}(:,2)=erase(DCRfile{k}(:,2),'kA');
DCRfile{k}(:,3)=erase(DCRfile{k}(:,3),'V');
DCRfile{k}=double(DCRfile{k});                 % converting string array to a numeric array

%Calculation of DCR
for i = 1:n{k}
    DCR{k}(i) = (DCRfile{k}(i,3))/(DCRfile{k}(i,2))*1000;
end

%Calculation of R(min) and Time at R(min)
[Rmin{k},Tmin{k}] = min(DCR{k});

%Calculation of Beta Peak
Rmax{k} = 0;
for i = Tmin{k}:n{k}
  % DCRx(i-Tmin+1)=DCR(i);
   if Rmax{k} < DCR{k}(i)
       Rmax{k} = DCR{k}(i);
   end
end
Beta{k} = Rmax{k};
Tmax{k} = find(DCR{k}==Beta{k}); %Time at Beta Peak

%Mean DCR
DCRmean{k}=sum(DCR{k})/n{k};

%Calculation of Heat Input
for i = 1:n{k}
    HI{k}(i) = DCRfile{k}(i,2)*DCRfile{k}(i,2)*DCR{k}(i)/1000;
end
THI{k}=sum(HI{k}); %Total Heat Input
end

[num,txt,raw{k}] = xlsread(myfilename);
               %   ^^^------- use xlsread to read the file with three outputs because csread supports only one

Hi madhan ravi

Is there any way to read the csv file.

[madhan ravi]

try readtable()

[Gagan Bansal]

not working.

[Gagan Bansal]

Is there any way to convert .csv file to .xlsx within the code?

[madhan ravi]

Why do you need three outputs? you seem to be using only the numeric datas right?

[Gagan Bansal]

Yes. my csv file is like:

250

1ms 1kA 10V

2ms 2.2kA 3V

3ms 3.6kA 5.4V

. . .

. . .

. . .

250ms 3.1kA 5.12V

I only need

250

1 1 10

2 2.2 3

3 3.6 5.4

. . .

. . .

. . .

250 3.1 5.12

[madhan ravi]

Well it had already been answered in your previous question so take a moment to read the answers in your previous question!

Answer 1

[Jeremy Hughes]

If you have both text and numeric data, I suggest you try READTABLE instead.

Answer 2

[M]

As the error says, you are requesting two many outputs arguments.

The function 'csvread' only returns one output.

[Gagan Bansal]

Is there any way to use csv file for multiple outputs.
