How can we solve the following pde by Maple? 

where v is velocity, v with dot is acceleration. (So, I think we will assume that acceleration is fixed.) And \delta is Dirac distribution.  E,I,m, M , g are fixed numbers.

Boundary conditions are:

Initial conditions are:

You can find the equation in the code: question.mw

Hello,

What are the methods for writing code to the recursive matrix A  as follows?

Thanks.

Hi;

I wrote a procedure. It includes two matrices which are H and psi. I highlighted the matrices in the following code.
I saved the file by using the following code. 

save newprocedure, "file.m";

In the other worksheet, I want to call and use these two matrices. 

How can I do?

You can find the following code for details.

procedure.mw

In the other worksheet; I can call one of these matrices, but I can' t call both of them.

restart;
read "C:\\Users\\PC\\Desktop\\file.m";
newprocedure(2);

After doing some calculations, the result includes 20 rows,  3 columns.

but it doesn't appear. How can we see the result?

Please find the following code?

Thanks.

I want to animate the functions approximate_f and f in the worksheet where 0<=t<=1.

Please find the following code.

Thank you very much.
