Hey Guys,

So if I have a function f(string) and I have a cell array i{j} of a set of strings, how do i do something like f('abc' i{j}) such that the arugment passed into f is the concatenation of 'abc' and i{j}

在 MATLAB Online 中打开

    x = {'abc', 'def','ghijk'};
    y = 'lmnop'; 
    x = char(x);
    x = reshape(x,1,size(x,1)*size(x,2));
    x = [y x];
    indices = isspace(x);
    x = x(indices~=1);

Then pass x to your function.

You look like your prepending your string in your post, so that's what I did. You may or may not care about the spaces.

I was confused by the question as well. I thought the poster was saying that input had to be a string to the function, not a cell array. Doesn't strcat('abc' ,x) create a cell array (where x is the original cell array of strings)

I would want to test to be sure, but I think If any input to strcat is a cell array, then the output from strcat is a cell array, even if all cell arrays involved only have a single entry.
