Dear community,
i am struggling with accessing cells in general and the function validateattributes() in specific.
I want to check the input of my function 'myfun(signals,_otherArguments)'. I expect signals to be of type cell and a row vector. This is easy enough:
validateattributes(signals,{'cell'},{'row'},'','signals',1);
Here are two signals for testing purposes:
badSignal = horzcat({'string1','string2',},cell(1,2), [3,4]);
goodSignal = horzcat({'string1','string2',},cell(1,2), 'string3');
Testing those variables will return nothing since they are both of type cell, just as intended.
But furthermore i would like to ensure, that the content of each cell is of type char while using the error massage handling of validateattributes.
This is where i am stuck.
validateattributes(cellfun(@ischar,signals),{'logical'},'positive'},'','signals',1);
This code is able to check each cells type but the error massage is quite useless to the user. For variable badString is Returns:
Expected input number 1, signals, to be positive.
As you can see the Input number -1- is correct but of course the Information 'expected positive' is not what i intended. Another idea is to loop through signals{:} and check every element with validateattributes() but this will mess up the Input number.
I hope I was able to clearify my Problem.
Any ideas how to check the type of each cell of signals while preserving the error handling of validateattributes?
