Assign Values into a matrix (DG)

hi

i'm a total novice to Matlab, i'm trying to assign individual values to elements in a Matrix,

EG

A 5x5 matrix

50 50 50 50 50 - Constant Value

0 0 0 0 0

0 0 0 0 0

0 0 0 0 0

0 0 0 0 0 - Constant Value

For 1st column and last column values should be decreasing to 0?

i.e

50 50 50 50 50 - Constant Value

37.5 0 0 0 37.5

25 0 0 0 25

12.5 0 0 0 12.5

0 0 0 0 0 - Constant Value

i would like to be able to do this for any iinputted size matrix, with constants always being teh same?

thanks

 matrix(:, 1) = linspace(matrix(1, 1), 0, size(matrix, 1));
 matrix(:, end) = linspace(matrix(1, end), 0, size(matrix, 1))
