MATLAB: MATLAB code error clarification

no arguments passed in when they're requiredwhy is that a problem?

Can anyone explain the error quoted below?

>> CalcMeasures

Not enough input arguments.

Error in CalcMeasures (line 3)

if size(Y,2) ~= 1

Best Answer

Your CalcMeasures function requires you to call it with at least one input argument. You called it with zero input arguments. Because of this MATLAB doesn't know on which data it should calculate the measures.

Just from looking at the code, it looks as though you're dividing a scalar by a column vector:

y = data(:,1);
...
...x(3)/(y.^2)...

This will result in a matrix right-divide, which will return a row vector. But

x(2).*(y.^2)

will give a column vector. And adding these together, of course, gives our good friend "Matrix dimensions must agree".

I suspect you want to do ./ instead of /.

MATLAB: Error message: “undefined function for input arguments of type ‘logical’ “

It indicates that there is no function by the name that you called for inputs of the logical type. So either you called a function that does exist, but you called it with an input that it didn't expect, or there just is no such function.
