MATLAB: Repeat a calculation for differently named variables

different named variablesrepeated calculation

Hi,

Any ideas on the shortest way to perform a calculation on several different named variables to give output of different names too?

For example, say I have variables a1, a2, a3 and I want to produce output named f1, f2, f3 all of which are defined as

f1=10(a1)+6 f2=10(a2)+6 f3=10(a3)+6

what would be the shortest way to do this?

The best way to do it is

a=[a1 a2 a3]
f=10*a+6

%instead of using many variables f1,f2 and f3, you have them in one

f(1)
f(2)
f(3)

Define the variables F1, F2, and F3 as symbolic variables.

syms F1, F2, F3
B = inv(A);
b = [0 F1 0 F2 0 F3 0 0 0 ]’;
x = B*b;

A = your Nx6 matrix
A(:,7) = sqrt(sum(A(:,1:3).*A(:,1:3),2));  % The RSS of the 1st 3 columns by row
