I've defined C and D previously and E and F are my unknowns. My code is
A = equationsToMatrix([C, D], [F, G]);
B = [ ];
X = linsolve(A,B);
result = double(X);
I know AX=B but in this case I don't know how to code B if it is to be the constants in the two equations C and D.
For example, if C = 0.011F-0.101G-0.555 and D=-0.028F-0.003G-0.055, Matrix A is [0.011, 0.101; -0.028, -0.003]. How do I get B to be [0.555; 0.055]?
Also, I'd rather not manually enter the values into B.

This should solve your problem:
[A, B] = equationsToMatrix([C, D], [F, G])

guys is there any way to solve the linear equations where the variables are present in both A and B arrays? please take a look to my question with more detail: https://uk.mathworks.com/matlabcentral/answers/416689-linear-system-of-equations
