MaplePrimes - answers and comments on Question, Can someone help me debug?

use the debugger

Consider doing what I did when you first posted this. That is, wrap your code into a Maple procedure, then use the Maple debugger to step through the code. That is, do

myproc := proc()
  (* all your code *)
end proc:

stopat(myproc):
myproc();

That will bring up the Maple debugger. You can execute each line one at a time, using the next, into, step, etc commands (read the ?debugger help page).

Invalid matrix/vector product

Executing this in Maple 13, the first error I get is "invalid matrix/vector product", and the offending piece of code has a red dotted line around it.

Note the dot between - and tan. That's what's causing the error.

Another mistake I see is that you have int(eqw1, bX .. cX, numeric) rather than int(eqw1, x = bX .. cX, numeric).

debug

joe riel, i wrote the code exactly as you said.. that didnt work

I looked into the debugging help page but this seriously confused me. so i opted for copying and pasting line by line to another work sheet and running it after each line.

i found that if my code looks like this

>x := something

> b:= something

>c := x * b

> d := x * b

maple finds the blank space on line 4 as an invalid object

if there is an extra space in the code for example x(space) :=something ... it is wrong

x:=(space)something.. it is wrong

I also found the errors pointed out by robert.

Thank you for helping
