Perhaps this —

per=5;
a=magic(4)

a = 4×4

16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1

apr = a*(1-0.05)                            % 95% Of The Value

apr = 4×4

15.2000 1.9000 2.8500 12.3500 4.7500 10.4500 9.5000 7.6000 8.5500 6.6500 5.7000 11.4000 3.8000 13.3000 14.2500 0.9500

apr = a*0.05                                % 5% Of The Value

apr = 4×4

0.8000 0.1000 0.1500 0.6500 0.2500 0.5500 0.5000 0.4000 0.4500 0.3500 0.3000 0.6000 0.2000 0.7000 0.7500 0.0500

ok but i want to use 5% and not: (1-5/100)....I thought there was a more practical way with matlab

[Star Strider]

I could not tell if you wanted to calculate 5% or reduce it by 5% (so calculating 95%).

This produces 5% —

format short g
a=magic(4)

a = 4×4

16 2 3 13 5 11 10 8 9 7 6 12 4 14 15 1

per=5;

apr = a*per/100                                % 5% Of The Value

apr = 4×4

0.8 0.1 0.15 0.65 0.25 0.55 0.5 0.4 0.45 0.35 0.3 0.6 0.2 0.7 0.75 0.05

I doubt that there is any other way to calculate it.
