Not enough input arguements

Hello i get the error " Not enough input arguments"

I have a function with 2 inputs. A variable called anz and a matrix (8x10). Matrix is a exported excel.

pls help

excelDatei = ' test.xlsx'
tabelle= 'tabelle 1'
zellBereich = 'A1:J9'
anz=height(matrix)
matrix=readtable(excelDatei, 'Sheet', tabelle, 'Range', zellBereich);

testfct(anz, matrix)
function [result 1, result 2, result3] = testfct (anz, matrix)
for i : anz
    element=matrix.ID(i)
    
end

[Stephen23]

After fixing a few syntactical bugs the code runs without error:

n = 5;
s.ID = [11,22,33,44,55];
testfct(n,s)

element = 11

element = 22

element = 33

element = 44

element = 55

function [result1, result2, result3] = testfct(anz, matrix)
for k = 1:anz
    element=matrix.ID(k)
end
end

stephen but whats wrong with my code. I get this error not on every compile but sometimes

[Torsten]

E.g. the line

for i : anz

will produce an error, but usually each time you run the code, not only sometimes.

"but whats wrong with my code"

As mentioned, there is a syntax error in the for loop. See - for; also, compare the for loop section in your code and Stephen's code.

You have specified 3 outputs for the function, yet the code does not define any of them.

It's not clear what you want to do. If you want to get all values of ID column/variable from table matrix, you can directly assign it like this -

element = matrix.ID;

If that is not what you want to do, please specify.

Additionally, use a semi-colon to suppress the outcome of the lines.

"I get this error not on every compile but sometimes"

Please show us the complete error message. This means all of the red text.

anz=height(matrix)

Put this line after readtable function where you read the data from Excel. The input to the function height is matrix and the output to the readtable function

[max muster]

I did. No change

Could the mistake be generally that i made my function with New --> new script instead of new function (is m file anyways) ?

[Dyuman Joshi]

Unless you are using R2016a or older versions, that will not be a problem.

Functions in a script are allowed with the restriction that they are defined at the end (bottom) of the script, which you have done.

You should check the comments above.

@max muster, As mentioned by others in comments to your question, there are syntax problems related to for loop inside the function. Generally the syntax for loop is

for i = 1:anz
  element(i)=matrix.ID(i)
end 
element % function outputs
