create matrix with rows and columns according to variables length?

[jfca283]

    Hi
    I need to create a loop. The issue is i have 2 variables, X and Y. And both are strings.
    So, how do i create a matrix with the form
    J(lengthX, lengthY, .)
    Besides, i need that the names of the rows and columns be according to the strings from X and Y.
    Using and example.
    The labels of X are 01 05 06 07 08 09 and Y are 01 02 03 04 05 06 08.
    So, i would need to create a matrix with 6 rows and 7 columns, naming the rows
    01, 05, 06, 07, 08, 09 and the columns 01,02,03,04,05,06,08.
    I know how to filled that matrix, but i have no idea declaring the number of rows or columns for the matrix. Also with the names of each one.
    Using the option destring doesn't suite me because i have labels as 011 and others as 11 which are completely different.
    Thanks for your time and interest.
    Really.
