Trigonometric Identities

This above Fractal code generates a small fractal mound in using the basic trigonometric operations. This involves a basic logic of an exponential surface that modifies the vector along the XY plane while the modifying function modifies the surface to yield a 3D likesurface as can be expected...

random_band is the main program and it outputs a test signal which has a constant level. The instanatenous frequency varies randomly within the specified Nth octave band range.The program outputs three plots: time record of the instantaneous frequency, time record of the instantaneous level, and...

COMPOSITE trapezoid Method for numerical calculations & analysis exercises in Numeric Integration. f function is given in terms of a symbolic variable x and as an inline function. E.g., f=inline('x^2+2*x-2'). Also, if the function f is trigenometric function, the 4th argument can be entered as...

Used to perform B*M or M*B with B a block diagonal matrix, B is stored as a cell array (call it C) with each element a matrix as a block of B, such that B = blkdiag(C{:}).This speeds up the multiplication when B is large and also allows the operation to take place when B could not fit in the...

Often I see students asking for help on a tool to compute the Fibonacci numbers. Or, I'll find them asking for help on a Project Euler problem. Or, a student has been assigned the problem of computing the fibonacci numbers using a recursive implementation. After all, these numbers lend themselves...
