25 Mar 2013 Slerp calculating a unit quaternion using a spherical linear interpolation (Slerp) Author: Sagi Dalyot

thx for the great file.
I have one last question:
You calculate the angle between both quaternions. But shouldnt you exclude the amount of rotation and calculate the dotprotuct only with the information of the axis? (Hence two 1x3 insted two 1x4 vectors?)

05 Jun 2012 Mutual Information computation A self-contained package for computing mutual information, joint/conditional probability, entropy Author: Hanchuan Peng

function 'mutualinfo' can not find function 'estpab'

where is the problem?

26 Apr 2012 2D Gabor Filter(Ver1,2,3) To design 2D Gabor filter and apply it to image. Author: Ahmad Poursaberi

I also recognized the missing imaginary part:
In General:
r*e^(i*phi) == r*(cos(phi)+i*sin(phi))

If you simplify r*e^(i*phi) to r*cos(phi) the you leave out the imaginary part. For this reason you needn't use 'conv2(imag(image))', because it's zero anyway.

So either add the imaginary part or leave out the imaginary part convolution to improve computation costs.

Or do I misapply your code?
