Indefinite Integral

Fresnel sine and cosine integrals should be done with quadl matlab function.

This program is a GUI for graphically demonstrating the convolution process. The user chooses two functions to convolve. The two functions are displayed, along with the convolution product and integral. The process can be animated if desired.

This include a MEX-DLL file which is an implementation of R L Siddon's refined method by Jacob for the calculation of ray path integral in PET/CT system image reconstruction. This is based on Line Intersection Length model to calculate probability matrix elements. Inputs are the LOR number and a...

Dynamical analyses in engineering often require inertial properties of complex shapes such as polyhedra. The volume, the first moment of volume and the second moment of volume of a general solid can be computed by V = Integral( dVol ), VR = Integral( R*dVol ), VRR = Integral( R*Rd-deOao*dVol )....
