Help me with this coding part

How to code these expressions r = r(x1,x2); rcap(x1,x2) = r(x1,x2)+x3*b3;

[Jan]

rcap(x1,x2) = r(x1,x2)+x3*b3;

This is valid code already. What exactly is your problem?

[Phanendra Kumar Attada]

symbolic variables, and function body must be sym expression.

Error in sym/subsref (line 909)

R_tilde = builtin('subsref',L_tilde,Idx);

Error in VAM (line 4)

THIS IS THE ERROR ITS DISPLAYING WHEN I RUN THIS
