I want to create 4 matrices (6x10) with sums of rows and columns as following; in a single program/code.

mat1::::sum_row1=sum_row2=......=sum_row6=r(say),,,,,,sum_col1=sum_col2=......=sum_col6=c(say)&&&&&&r=c

mat2::::sum_row1=sum_row2=......=sum_row6,,,,,,,,,,,,,sum_col1≠sum_col2≠......≠sum_col6

mat3::::sum_row1≠sum_row2≠......≠sum_row6,,,,,,,,,,,,,sum_col1=sum_col2=......=sum_col6

mat4::::sum_row1≠sum_row2≠......≠sum_row6,,,,,,,,,,,,,sum_col1≠sum_col2≠......≠sum_col6

Kindly suggest some logic/program

Thanks
