Re: I have 51 linear equations, consisting of 51 unknowns. How to solve it in Matlab by using matrix?

> What do you mean by "separate the equations"?
Let say I have 3 equations with 3 unknowns. 1x1 + 2x2 + 3x3 = 100 4x1+ 5x2 + 6x3 = 200 7x1 + 8x2 + 9x3 = 300
Normally in Matlab, you will do this command in order to solve x1,x2,x3
p=[1 2 3; 4 5 7; 7 8 9]' q=[100 200 300]' x=inv(p)*q
But let's say I don't want to use the method/way that I write. What other options that I have in order to solve for the 51 unknowns?
