28 Aug 2010 ScaleTime Fast linear interpolation of equally spaced data (C-MEX and M) Author: Jan Simon

@Ed: This is a section for "Comments and Ratings". Please explain your problem with the necessary details in the newsgroup.
23 Aug 2010 ScaleTime Fast linear interpolation of equally spaced data (C-MEX and M) Author: Jan Simon

@Ed: Further problems: As you can see in the documentatoion, ScaleTime is designed to be fast is the original ticks are [1:length(Y)]. If your yVector is something different, you have to consider this in the calculation of dR.
If the compilation fails, there is still the M-version of ScaleTime. So if "which('ScaleTime')" does not find the function, you have to include it in your path.

@Ed: Did you compile the C-function or downloaded the corresponding pre-compiled file? If you did, is the compiled mex file visible in the path?
Is it really needed to start the interpolation for each scalar dR(I) and each vector rcCorrected(:, ii)? The interpolation is much faster, if you perform it for matrix data and vector time points.
10 Aug 2010 Directory to Cell Converts directory listing into a cell array. Author: Kevin Crosby

H1-Line, descriptive help section, example, date, version number, author with contact address, working, usable.
If you need the reply of DIR as cells and vectors instead of the standard struct format, this will be helpful.

You can create vectors without the slow CELL2MAT:
  datenums = cell2mat({d.datenum}');
=> datenums = [d.datenum]';

09 Aug 2010 COMBINATOR -combinations AND permutations Returns 1 of 4 different samplings on the set 1:N, taken K at a time. Author: Matt Fig

Your first submission contained the source code cumsumall.cpp. Now I find only the compiled mexw32. It would be nice to have the source again, to allow all non-Windows and the 64 bitters to work with COMBINATOR.

26 Aug 2010 ScaleTime Fast linear interpolation of equally spaced data (C-MEX and M) Author: Jan Simon Santana, Ed

I looked at my yVector and it is something different than [1:length(Y)]. The reason im trying to find something faster to replace interp1 is because i managed to increase the speed of all the other major functions in my code with Jacket v1.4. Besides ScaleTime do you know any other way to increase interp1 with Jacket?

Yes i tried to compile mex -O ScaleTime.c but i get error mex: compile of ' "ScaleTime.c"' failed. I cannot use the pre compile mex files because I'm using MATLAB 7.9(64-bit). The purpose of my code is to output a Radar image, from my understanding dR(I) and rcCorrected(:, ii) provide the value for each pixel in the image. How do you recommend i rewrite this for matrix and vector time points?
