Hi all..

After i evaluated an answer using matrices..the resulting answer is stored in a Matrix..but im not able to see the anwers instead it displays...11 x 1 Matrix...DataType:anything....storage: Rectangular..Order: Fortran Order...wat to do to make the results display?

thanks.

i am deriving lagrangian shape function symbolically for an 1-D element of order p in FEM....so the eleemnt will have p+1 nodes....

                                   N(k,i) = product((X-Xother)) / product(Xcurrent-Xother)

de := diff(theta(t), `$`(t, 2))+c*(diff(theta(t), t))+9.8*sin(theta(t))/L = 0; c := 2; L := 2;
init := theta(0) = 0, (D(theta))(0) = 4;
sol := dsolve({de, init}, theta(t), numeric, output=listprocedure);
Theta := subs(sol, theta(t));
plots[animate](plots[arrow],[[0,0],[L*sin(Theta(t)),-L*cos(Theta(t))],colour=red],t=0..5, axes=none,scaling=constrained);

these lines of codes were posted by robert Israel in one of his posts.

it would be of a great help if anyone share the companion CD of

is there any way that cartesian eqns can be converted to parametric  and vice versa in maple?

solve(exp(-x)-x = 0)

gives 'LambertW(1)' intead of '0.56' which i found by simple fixed pt iteration.

how to covert function to expression???

What are those 'Z' s represent?[File is attached]

hi all....how to find pseudo inverse in maple...like the one 'pinv' in matlab.

is there any command to generate identity matrix,zero matrix

thanks

hi all...i want to write a procedure just to execute a set of maple commands without any input args e.g do some calc and plot series of graphs..i am facing 2 problems

1.inside procedure all lines are not  displayd only last line of command inside the proc is diplayed after execution

2.im choosing a proc to exec a series of commands because i can use the debugger to debug the set of codes else i cannot.
