Case and Space Sensitivity

MATLAB is case sensitive. For example, you cannot run the function Plot but must instead use plot. Similarly, the variable a is not the same as the variable A. Note that if you use the help function, function names are shown in all uppercase, for example, PLOT, solely to distinguish them. Do not use uppercase when running the functions. Some functions for interfacing to Java actually used mixed case and the M-file help accurately reflects that.

Blank spaces around operators such as -, :, and ( ), are optional, but they improve readability.
