I have a data matrix 17000×4 cell type and other cell matrix type 49000×38 containing both text and numerical data . The first column of the second matrix contains 49000 numerical labels elements while the first column of the first array contains 17000 examples of some of these labels . My goal is to create an array containing the values of the columns 2:38 the second matrix corresponding to each of the examples 17000 . In short , I want to look for each example corresponding feature vector contained in the second matrix.
I want to do somthing like this but using vectors instead single values for each key: http://es.mathworks.com/help/matlab/matlab_prog/creating-a-map-object.html#brq_zd0-1
