Cell array as input function

I have a certain function that I need to use:

[t3_1_HR,q3_1_HR,qd3_1_HR,Tact3_1_HR,TSRS3_1_HR] = SimulatePendulumTest(m, kF, kdF, d, Tb, 1, tspanHR);

And I have a cell array with different tspanHR's (every row is a subject and each column is the number of HR files per subject). I want to know every outcome of the function for the different tspanHR values. How can I do this?

Thank you very much!

You can use cellfun to apply your function to each cell.

[t3_1_HR, q3_1_HR, qd3_1_HR, Tact3_1_HR, TSRS3_1_HR] = ...
    cellfun(@(x)SimulatePendulumTest(m, kf, kdF, d, Tb, 1, x), YourCellArray, 'uni', false);

You do need to be carefull with the empty elements of tspanHR.

% example
x = {1, 2, 3;4, 5, 6}; x{4} = [];
x =

  2×3 cell array

    {[1]}    {[       2]}    {[3]}
    {[4]}    {0×0 double}    {[6]}
    
foo = @(x, y) x + y;
outMe = cellfun(@(x, y)foo(x, 2), x, 'uni', false)

2×3 cell array

    {[3]}    {[       4]}    {[5]}
    {[6]}    {0×0 double}    {[8]}

UniformOutput takes care of non scalar values of x.

[Rik]

It does, but your function should do that as well. cellfun does not automatically skip empty elements.

A=rand(2,3);
cellfun(@(x) size(A,x),{1,[]},'UniformOutput',false)

Error using size
Dimension argument must be a positive integer scalar or a vector of positive integers.

Error in solution (line 2)
cellfun(@(x) size(A,x),{1,[]},'UniformOutput',false)

Oops! I see, you are absolutely right, I assumed user function in the simplest form.

A = rand(2, 3);
input = {1, []};
cellfun(@(x) size(A, x), input(~cellfun(@isempty, input)))
