Using PHP's session_start(); more than once? Will it clear the past session's variables? I'm currently developing in PHP, and I need to know if using More than once in a script, or on a page/site will clear the variables or have any effect? If so how can I use this dynamically...
Many beginners write scripts that create lots of variables. Then the beginners want to get rid of their variables and so they write clear at the beginning of every script. The proper solution to this is not to use clear, but to write functions. It really is that simple! Advanced MATLAB u...
Workspace variables do not persist after you exit MATLAB. Save your data for later use with thesavecommand, save myfile.mat Saving preserves the workspace in your current working folder in a compressed file with a.matextension, called a MAT-file. To clear all the variables from the workspace...
You can create x1g and x2g using the MATLAB meshgrid command. Given two free variables, x1 and x2, you can create the first and second coordinate matrices of a grid by entering: >> [x1g,x2g]=meshgrid(x1,x2); To summarize, here are the req...

The MATLAB debugger is cleared (dbclear all) before each execution, as interactive input is not supported by the engine API. Differences with the Calysto MATLAB Kernel History is read from and written to MATLAB's ownHistory.xml, and thus shared with standard MATLAB sessions. Note that if the...
