Good Morning. Waiting for your valuable help. How to replace the values obtained in D in the matrix A and so on and that this is done 5 times.
clc; clear; close all
A=[0 0.84 1.62 2.19 2.69 3.56 4.55 5.11 5.95 6.94;
0 0.71 1.61 2.19 2.87 3.83 4.79 5.62 6.56 7.06;
0 0.93 1.49 2.48 3.15 3.73 4.27 4.86 5.77 6.76];
B=[0 0.84 1.62 2.19 2.69 3.56 4.55 5.11 5.95 6.94;
0 0.71 1.61 2.19 2.87 3.83 4.79 5.62 6.56 7.06;
0 0.93 1.49 2.48 3.15 3.73 4.27 4.86 5.77 6.76];
C=A+B;
D=2.*C
Thank you

Please provide the exact desired result for your example. I.e., spell out the values of the result so we can be sure we understand what you want.

Hi. Thanks for addressing this doubt. If we introduce the values of matrices A and B to MatLab, we will obtain the value of D
0 3.3600 6.4800 8.7600 10.7600 14.2400 18.2000 20.4400 23.8000 27.7600
0 2.8400 6.4400 8.7600 11.4800 15.3200 19.1600 22.4800 26.2400 28.2400
0 3.7200 5.9600 9.9200 12.6000 14.9200 17.0800 19.4400 23.0800 27.0400
Now these values obtained replace them with the values that A and solve the operations C = A + B; and D = 2. * C obtain other values of D and these in turn replace the values that A had and repeat the process 5 times. I hope I have explained better. Thank you

Is this what you want?
A=rand(3,10);
B=rand(3,10);
C=A+B;
D=2.*C;
for k=1:5
A=D;
C=A+B;
D=2.*C;
end
