ksdensity support parameter
Hi, I'm trying to estimate an inverse cdf and I'm having the following problems: When I estimate: x1 = ksdensity(x,u1,'function','icdf'); I get negative values for x1 even though the supports for both u1 and x are positive. When I try to correct this by estimating: x1 = ksdensity(x,u1,'function','icdf','support'... 10 Mar 2010 15:19

Frequency Plot to one third octave bar chart
Hi, I have sound pressure level and Frequency from the following: [MIC1,Faxis] = cpsd(mic1,mic1,win_shape,noverlap,block_len,fsamp); I can plat his as Sound Pressure Level vs Frequency giving but how do I get this in one third octave form, as in a bar chart with frequency on the x-axis and dB level on the y-axi... 5 Mar 2010 15:04

finding main path and branch from a graph(3D image)
I have a 3D image which contains a graph (centerline of a main vessel and its branch). I want to extract the main root and its separate branch in 3D. In our difinition the the main root is the longest path and it can be a curve structure in 3D. The line-end voxels (end of branch and main root or in the other view the ... 5 Mar 2010 15:04
