Factorial of large numbers This function implements a standard algorithm for computing factorials. It may not be the most efficient for very large arguments, but it is very transparent. The function accepts single numbers as inputs or arrays.Note that for any real work, the code suggested by John D'Errico is actually...

Log of factorial of large numbers This function computes log10 of the factorial. Unlike FACTORIAL, it is not limited to arguments less than 171.Two methods are implemented, one based on the gamma function (thank you, John), as well as a direct sum. The user can choose between the two methods. The gamma method is superior and is...

A dice roller for Matlab SYNOPSIS: [total, details] = roll(str)INPUT str: Dice to be rolled. XdY, where X and Y are scalars, rolls X fair Y-sided dice. Both X and Y are necessary. If str is empty or omitted, '1d20' is used as default. ROLL replaces the dice expression(s) by the rolled result, and then evaluates the...

Symbolic polynomials A polynomial is a mathematical expression involving a sum of powers in one or more variables multiplied by coefficients. A general multivariate polynomial is captured with the syntaxp = sum( c_i * prod( x_j^p_ij ) ) + kwhere the summation is over i, the product over j, and c_i is the set of...

Fast interpolation This function performs interpolation faster than MATLAB's "interp1" function. In the limit of small library and search arrays, it is ~5x faster. In the limit of large library arrays, qinterp1 has a flat scaling, while interp1 has a linearly increasing scaling (see the image for this file)....

2D minimal bounding box Compute the minimal bounding box of a set of 2D points, similarly to the "Minimal Bounding Rectangle" of John D'Errico.However: - The algorithm is fully vectorized (matlab implementation, no for loop). Thus it is better for big set of points - It computes only the minimum area rectangle, not the...
