I've got a Jacobian matrix defined in my maple code to be:
The matrix consists of expressions involving the variables R,X,Y,Z,t where R:=(X2+Y2+Z2)0.5
I wish to evaluate the matrix for X=1, Y=1, Z=1, t=1ONLY. but I want to leave R alone. I've tried using the code:
but Maple evaluates it for all the vaiables including R.
