How can I adjust data to make it a percentage of 1000

I have a fixed 3x14 matrix and need to divide each row by the total sum of the matrix then multiply it by 1000 so it appears normalised to 1000 on the Y axis of a bar chart it feeds into, but am unsure how to do it

A = rand(3,14) ;
thesum = sum(A(:)) ;
iwant = A/thesum*1000 ;

thank you! will rand not give me random values? I already have the values in a matrix called mix2, can I replace rand with mix2?
