Dear @Markiyan Hirnyk first of all I am very thankful your positive response. I did the changing according your instruction but could'nt find results becuase maple sheet take alot of time to evalute. Please see the attachment and see why they takes to much time. I want to produce reuslts for M=N=100. Again thanks in advance.

Dear @Kitonum first of all thanks alot for your positive answer. You almost fix my problem but I need answer in form that the denominator seprate with each term then simple.

dear @taro first of all thanks for your answer! I want to covert diff(u,y) into diff(U,Y) with u=v/d^2*U(Y), and y=d*Y. Manually I do in the attachment, which can help to fix the problem.

Dear @Carl Love thanks for your answer. I need the inverse laplace of F(q, x, alpha) that is invlaplace(F(q, x, alpha),q,t) then I want to plot it for fix values of t and alpha for x=0..1. 

Dear @vv; thanks for your precious time and valuable suggestions. 

I know each and everything. If you can solve my problem then reply. I am not free to see your bloody answer.

@Preben Alsholm 

Thanks for your kind answer. Now my one more question is which method (buiton command) is best to solve system of nonlinear ODEs numerically. Beacuse some time I face the error like this mehtod is not converges.

Dear Sir! I want to see the values of F(eta), G(eta) and H(eta) form 0 to 1 with 0.1 difference. I need the accuracy till 13 decimal places please correct the program accordingly, Thanks for your psoitive response.

@Carl Love 

Really thanks alot for your kind efforts. But still there is problem when I compare the coefficient having "x power 0" (used the command remove(has,f, x)). Please solve the problem the problem is attached.

Dear friend!

I am very thankful you kind effort. Your file which you sent me I used it to found the solution for H=[0,1000,2000,3000,4000] using your program (attached). Then I calculate the solution using my program (attached) for the same values of H but they are different. My results are correct but I want to calculate the same result using your program. Please let me know where is the problem because solution dosent match. Your program more better than me, and convient to use. I am waiting your positive response.

Dear Sir I want to plot the above graph from -1..1 where the change will happen? I am waiting your positive response. 

@John Fredsted I required a sepcial lower triangular matrix as shown in attached fine. I know the built-in command which you sent me. If you fix my problem, i will be grateful to you. Thanks
