cadd Complex addition of two arrays
cceil Computes ceil for a complex array
cconj Conjugated array
ccos Complex cosine
ccosh Complex hyperbolic cosine
cdiv Complex division
cexp Complex exponential
cfloor Computes floor for a complex array
cimag Extracts imaginary part of a complex array
cinv Complex inverse matrix
cln Complex natural logarithm
cmatdiv Computes the complex solution of A x = b
cmatmul Computes the complex matrix multiplication of X and Y
cmul Complex multiplication
complex Generates a complex array
cplot Plot of x and y in absolute space
cplotfunc Plots a function of x and y-space
cpolar Complex numbers in polar coordinates
creal Extracts real part of an complex array
csin Complex sine
csinh Complex sine hyperbolicus
csort csort sorts the rows of a complex matrix with respect to the absolute value of the complex numbers. If a column c is specified the rows of the matrix will be ordered with respect to the elements of column c in ascending (descending) order.
csortcol sorts with respect to either a real part of a column or an imaginary part of a column c. If 1 <= c <= cols(xr) it sorts after the real part of x, if cols(xr) < c <= cols(xr)+cols(xi) it sorts the imaginary part after column c-cols(xr).
csqrt Complex squareroot
csub Complex subtraction two arrays of complex numbers
ctan Complex tangens
ctanh Complex tangens hyperbolicus
eiscg Computes the eigenvalues and eigenvectors of a complex general matrix
eisrg Computes the eigenvalues and eigenvectors of a real general matrix
eisrs Computes the eigenvalues and eigenvectors of a real symmetric square matrix
ErrDLL This macro evaluates and displays error-messages from the eispack.dll, eispack.so respectively.
mat2rot Decomposes an orthonormal matrix into a set of rotation matrices.
mathmain sets defaults for library math
mathtest executes some tests for the macros defined in math.lib.
orthonormal Computes a orthonormal system of column vectors using the Gram-Schmidt procedure.
qp0 solves a quadratic optimization problem with linear inequality constraints
rot2mat Computes an orthonormal matrix from a set of Givens rotations.
