Hello,

I am quite new to Maple and require some help on vector calculus. I have a differential operator in matrix form C that has to be applied to a column vector B.

C = [d/dx   0    d/dy]

      [0     d/dy  d/dx]  

and

B = [

Hey,

suppose I have got two quadratics varying with variable Q1 and two quadratics varying with Q2,

eg. P1=a+b*Q1^2 and P11=c+d*Q1^2

     P2=e+f*Q2^2 and P22=g-h*Q2^2

where a,b,c,d,e,f,g and h are finite constants such that curves P1 and P11 intersect at two values of Q1, one being negative and the other positive. The same is true for curves P2 and P22. Now, I can plot curves P1 and P2 on a 3D plot (x-axis = Q1 and y-axis=Q2 and z-axis=P1=P2...

Hi,

Basically I have two curves, P1 and P2, which are dependent on Q1 and Q2 in a square manner. For example, P1:=1+Q1^2 and P2:=5-Q2^2. I now want to plot P1 and P2 on the same graph with the values of P1 and P2 on the same z-axis and Q1 and Q2 along the x- and y-axes. Consequently I would get two orthogonal parabolic curves. plot3d([P1,P2],Q1=-1..1,Q2=-1..1) doesn't work because it obviously draws two surfaces rather than two curves for P1 with Q2 always equal to...

Hi,

I have created a matrix of 101 rows and 93 coloumns and then populated the matrix via various loops. The values in the matrix are the values of a specific parameter G which varies with k and e. The rows represent values of G with constant values of parameter k while the coloumns represent constant values of parameter e. So if you imagine the matrix being a table one side represents values of e and the other side...
