thank u, i do the step which u refer to it in your answer but their exist error and the following message is appeared
??? Error using ==> mesh at 80
Z must be a matrix, not a scalar or vector.
code according to your vision
for x=0:0.1:1;
syms s % s is symbols
v=char(x./(s^2+1)); % v is function of (x,s)
% numerical method to compute inversion Laplace transformation
% this function is available through remark at below
[t1,ft1]=INVLAP(v,0.0001,5,1000,6,39,89);
end
mesh(x,t1,ft1)
