Is it possible to solve the following ???

Hello everyone I need to ask a tough question I have an integral I should plot in 3d from minus infinite to plus infinite it is known that this integral is hard but can be solved numerically I need it in matlab is it possible???? How should I start if I have an integral from minus infinite to plus infinite of Exp(-xpower2+(exp(-xpower2))) ????? Is it possible if so how can I plot in 3d the square of this function?? I hope someone has the answer thank you

If I understand your notation correctly, the integrand you describe is one-dimensional. In what way does it lead to a 3D plot?

I believe the matlab function 'integral' will accept plus and minus infinities as limits of integration.

Actually the intergal is more than one variable omega and time as in Fourier transform so I want to show in 3d a pulse i have been told that this function can be solved numerically such that we can plot it after wards in 2 and 3 dimensions do you have any thoughts on how can that be possible

[Roger Stafford]

The matlab functions integral2 and integral3 will also allow infinite integration limits.

Does it work in matlab2010 or just in 2013???

[Walter Roberson]

It was after R2010 if I recall correctly.
