Hey guys, I'm trying to create a matrix with combined math operations from already defined variables in the workspace but I always get an error. I would really appreciate some help :)
Variables :
c1=440
c2=250
r1= 50
r2=25
Matrix :
C=[c1*r1^2, c1*r1*r2, 0;
c1*r2*r1, c2+c1*c2^2, -c2;
0, -c2, c2]

For me, it works fine.

Ran in:
c1=440 ;
c2=250 ;
r1= 50 ;
r2=25 ;
C=[c1*r1^2, c1*r1*r2, 0;
c1*r2*r1, c2+c1*c2^2, -c2;
0, -c2, c2]
C = 3×3
1100000 550000 0 550000 27500250 -250 0 -250 250

this code is right.
c1=440
c1 = 440
c2=250
c2 = 250
r1= 50
r1 = 50
r2=25
r2 = 25
C=[c1*r1^2, c1*r1*r2, 0;
c1*r2*r1, c2+c1*c2^2, -c2;
0, -c2, c2]
C = 3×3
1100000 550000 0 550000 27500250 -250 0 -250 250
there could other reasons for the error.
