Create a correlation matrix for variables in the data, MATLAB Programming

In MATLAB, create a correlation matrix for all of the variables in the data (it should be an 8x8 matrix). To do this you will have to convert the "southern"variable into a number. Helpful hints: (1) To access the first row and column of a cell array you need to use curly brackets (row1col1=cellarrayf{1,1}) and (2) To compare 2 strings use the strcmp function.
