PRIME_PLOT is a MATLAB program which displays a "box plot" of the prime and composite numbers.
An N by N grid A of squares is displayed. If N is prime, then the squares A(N,1:N) are red. If N is composite, then A(N,D) is blue for each divisor of N.

PRIME_PLOT is available in a MATLAB version.
BOX_DISPLAY, a MATLAB program which displays a box plot, over integer pairs of data, of a function defined by two formulas.
PRIME_PARFOR, a MATLAB program which counts the number of primes between 1 and N, running in parallel using MATLAB's parfor feature.
PRIME_SERIAL, a MATLAB program which counts the number of primes between 1 and N, intended as a starting point for the creation of a parallel version.
PRIME_SPMD, a MATLAB program which counts the number of primes between 1 and N; running in parallel using MATLAB's Single Program Multiple Data (SPMD) feature.
