## some matrixs...

All the matrix can be an enforceable Square matrix.

I put some Matrix for some parameters.

Thanks so much

## M is a Matrix...

Thanks so much.

I wrote the code according to the following equations.

Yes M is a Matrix. if possible, please see this file. (see the text after Eq (17))

## other Matlab syntax ?...

@Carl Love
What is the Maple equivalent of the Matlab syntax  size(M, 1) and length(T) and zeros(N, lt) and

A\D?

thanks

## plot...

Thanks.

How I can save the results ''''XT(timeCounter+1)'''' and ''''TT(timeCounter+1)'''' and then plot XT versus TT.

Also, why the value of [evalf(Re(totalTerm))] is not real?

## numerical methods...

Dear Preben

Is possible to solve this differential equation by numerical methods such as FDM and Newmark Method?

## input parameters...

Thanks so much.

If it is need to change the input parameters, I have not any problem in this regard.

I only want to gain an answer!

Best Regards,

## numerical methods...

Thanks so much,

Is possible to solve this equation in maple via numerical methods?

Thanks

## This is not possible?...

This is not possible?

Thanks so much

## procedure of solving...

I probide again procedure of solving.

## Thank you......

Thank you.

From the beginning, my mean problem was about the new file that I sent recently.

For now, I want to follow the same procedure to remove qx-qy and qz.

the procedure is the same as you apply in simpProb2.mw. Only in the new file, more terms appear. But formulation is fixed, and I want to remove any terms with derivatives concerning q-x, q-y, q-z

## I could not apply........

Thank you so much.

I could not apply your procedure on the new attached file.

## The procedure...

Thank you so much.

In attached pdf file below I explained better about my mean. Please see it.

This file is related to the maple file with the name of (simpl.mw).

As you can see in the final equation (Eq 10) qx-qy-qz are omitted.

Now I want to use the same procedure and apply this method on maple file with the name of (simpl2.mw)
