Recent versions of MATLAB have strings, which are N-Dimensional matrices of character vectors. I have a cell array of such 1D strings that I would like to combine into a single 2D string, but I am having a lot of trouble doing so. The join, strjoin and strcat functions work on the characters arrays inside the string, and cell2mat doesn't work:
>> cell2mat({strings(1, 4); strings(1, 4)})
Error using cell2mat (line 52)
CELL2MAT does not support cell arrays containing cell arrays or objects.
Is there any good way to do this? I expect the output in the above case to be a 2x1 string object.
string objects behave just like any other datatype (double, char, etc.) when it comes to concatenation with the same type. As long as you want the result to also be a string object, use normal concatenation.
result = [strings(1, 4); strings(1, 4)];
Or you can use cat or vertcat to be more explicit
result = cat(1, strings(1, 4), strings(1, 4));
result = vertcat(strings(1, 4), strings(1, 4));
Alternately you could use indexing to sample the same element twice
result = strings([1 1], 4);
If your data is already in a cell array, then you can use {:} indexing to generate a comma-separated list that you can pass to cat
C = {string('one'), string('two')};
result = cat(1, C{:})
As a side-note, there is no such thing as a 1-dimensional array in MATLAB. All arrays are at least two dimensions (one of which can be 1).
