Very helpful!
Thank you.

very exciting option.
It can be interesting include of your option as apart of publish MATLAB function.
Or may be you know how to do that ?

04 Aug 2011 Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan

You are right, I can't because of the work.
Sorry.

30 Jul 2011 Read ZEMAX Beam File (ZBF) Reads a ZEMAX Beam File into Matlab, allowing presentation of physical optics simulation results. Author: Sean Bryan

thanks for replying. I needed this solution for my work. After all we solved this problem in native MATLAB by using description from ZEMAX support of ZBF file structure. We made it with only using binary file functions.

I use WIN 7 and after installation of MinGW and GNUMex the line mex read_zbf_mex.c didn't work. Also mex -setup doesn't recognize this compiler.

The description of how to compile file is poor.
1. Please let more instruction for using.
2. Is it possible to write same function without using mex file (fopen, fread, ...)?

10 Apr 2014 Shortest Distance Between Two Lines in N dimensions Function calculates shortest distance between two lines presented by two points for each line. Author: Alexander Brodsky Steve

Works fine, thanks!

01 Apr 2011 Shortest Distance Between Two Lines in N dimensions Function calculates shortest distance between two lines presented by two points for each line. Author: Alexander Brodsky Brodsky, Alexander

Thanks Guy. I corrected the mistake and made some changes for better running. The main of them is the change of the dot function to matrix multiplication. Dot function takes relatively long time. It was checked in the Profiler.

There is a bug in the code which determines the points along each line where the point of closest approach exists. This is because the distance between the lines uses the variable 'd'. But 'd' is previously set to 'd=dot(u,w0)', and is then needed to calculate 'sc' and 'tc'. So now 'sc' and 'tc' (which calculate 'Pc' and 'Qc') are using the wrong 'd'. This bug is simply fixed by moving the lines calculating 'sc' and 'tc' up a couple lines so they're above the overwriting of 'd'.

This bug is visually VERY obvious if you execute the commented plot script. Also can be verified by checking the length of Pc-Qc compared to the solution for d.
