when i prompt a user for a value for m,n how do i attain a matrix such that the first row of a matrix be 1 to m for eg.if a user input a value of 9 for m the first row of a matrix will be: 1 2 3 4 5 6 7 8 9
similarly, if the user enter a value of 6 for n, then my first column will be 1 2 3 4 5 6
please kindly advise,thanks alot!

You have not said how you are filling in the other entries of the matrix.
We can't have the user get 9 columns with your row vector and then have one column of 6 elements. You have created a 9x6 matrix, how do you want us to fill in the missing elements?

See my comment above. If you want us to fill the remaining elements with zeros.
dims = input('Provide the row and column dimension of the matrix in brackets, e.g. [6 9] \n');
% the user enters [6 9]
X = zeros(dims(1),dims(2));
X(:,1) = 1:dims(1);
X(1,:) = 1:dims(2);

You changed your code so now it works, initally you had the wrong numbers in your column and row assignment.
The above will work but you are just filling the last column and last row, is that what you want?
