In general, the problem is that the spacing between points determines the "importance" of a particular point. For example, if several points are very close together, then small amounts of noise on those measurements will tend to have a greater effect on inferring the slope of the function (and with it, the high frequency energy) than the same amounts of noise on measurements that are further apart. Buy MathWorks MatLab R2009b You can use "depfun " from the File Exchange. "Suppress appearance of the MS-DOSmand window when generating a standalone application. Use -e in place of the -m option. This option is available for Windows only. Use with -R option to generate error logging as such: Matlab is huge area The causes for crashes are many andplex, andplicated to figure out, especially if you don't have access to the source code. This is why it's best for The Mathworks to work on your crash issue. Call The Mathworks at (508)647-7000 and explain to them the circumstances for your crash. The Mathworks gives free support for all installation problems, even by telephone and even for Student, Home, or Trial versions. Note, this is just if MATLAB itself crashes, not if it's your m-file throwing an error (red text in themand window) or a DLL or mex file causing the crash. Buy MathWorks MatLab R2009b The license will be automatically updated by Matlabmunicating with the Mathwork site. Make sure you restart Matlab after this process is done. One choice is the image processing book written by Steve Eddins. Steve Eddins is a software development manager in the MATLAB and image processing areas at MathWorks. Steve coauthored Digital Image Processing Using MATLAB. He writes about image processing concepts, algorithm implementations, and MATLAB, both in the book and on his Steve on Image Processing blog.

NOTE: If you do not have one, you will be given the opportunity to create a MathWorks account at this point. A MathWorks account is REQUIRED to use Matlab. You must use your netid@Princeton.EDU email address as your MathWorks email address. Please do NOT use your LDAP or Windows University password as your MathWorks password. NOTE: If you are a student and previously created an account with MathWorks for the student version of MatLab, you will need to login to the MathWorks website before installing R2009b, and change your profile from " student " to " academic ". Image Processing Toolbox Edit From the Getting Started book: 1) Using globals is perfectly okay (that's why they are there in first place), just like for's and while's and other intelligent 2nd generationputer language constructs (that MATLAB is built on), as long as you are careful about where, why, and how you use them. To do this correctly, you need to use the "functional" form of save: Why is my MEX file crashing? Edit Another approach is to use structures with dynamic field names instead of cell arrays. The fields of the structure can be the variable names you want. And you can index into them with dynamic field references. For example: How can I find local maxima in a vector array? Edit Why can't my standalonepiled executable find my files? Edit The EVAL function is one of the most powerful, flexible, and potentially dangerous functions in MATLAB. Since EVAL is so powerful, it is easy to misuse the function. In a way, the EVAL function is a lot like global variables; both are tools that are so easy to use that it might be easier to use them rather than to search for a more elegant, safer, and appropriate solution. There is a major drawback to the EVAL function, although it can be avoided if you use EVAL carefully. EVAL can be used to alter arbitrary variables. In addition, two related functions, evalin and assignin, can be used to alter variables in different function workspaces. These functions can create bugs which are difficult to reproduce and nearly impossible to eliminate. Further explanation, and The Mathworks official warning against using eval, can be found in Mathworks Tech Note 1103.
