Hihi,(adsbygoogle = window.adsbygoogle || []).push({});

Let's say I have the linear equations ,A

2x +3y +4z

5x+6y-7z

5x-4y+3z

then I can always write as a matrix multiplication A= B*x

matrix B =

2 3 4

5 6 -7

5 -4 3

times

matrix x

x

y

z

Then., how can I tell matlab to express in the matrix multiplication form so that I can only have B.
