determine if array contains specific integer in octave

Question

I have an array which looks like

test = {1,2,3};

I want to determine if an integer belongs in the array. I tried using ismember() and any() but they both return this:

binary operator '==' not implemented for 'cell' by 'scalar' operations

How will I do this? Thanks in advance

Answer 1

If you want to check if an integer exists in a matrix:

test = [1, 2, 3];
any (test == 2)
ans =  1

But in your question you use a cell array. In this case I would first convert it to a matrix, then do the same:

b = {1,2,3};
any (cell2mat (b) == 2)
ans =  1
