A guide to MATLAB : for beginners and experienced users : updated for MATLAB 8 and Simulink 8 / Brian R. Hunt, Ronald L. Lipsman, Jonathan M. Rosenberg, all of the University of Maryland, College Park.
Boolean algebra can be done in MATLAB using the logical operators AND (&) , OR (j) and NOT (˘). For example given an arbitrary boolean variable S: >> S | ~S ans = 1 Note: MATLAB implicitly "casts" data types to avoid syntax errors: Logical values are converted to 1 and 0 when used as numbers. >> (2 < 3) * 3 ans = 3 >> true * 3 ans = 3
Y = log(X) returns the natural logarithm ln(x) of each element in array X. The log function’s domain includes negative and complex numbers, which can lead to unexpected results if used unintentionally.
