I have a 1x601 cell array containing text and a 1019x601 double matrix. I am trying to merge the arrays using vertcat but I get "dimensions of matrices being concatenated are not consistent." Theoretically I should get a matrix that is 1020x601. What am I doing wrong? Thanks.

It might mean that not all the strings in the cell array have the same length and therefore you cannot concatenate them.

You need to work with cell arrays in order to support mixed numeric and string data. To use vertcat, convert the double matrix to a cell first.
Example:
A = rand(5);
B = {'apple','pear','banana','orange','peach'};
vertcat(num2cell(A),B)
