Some of Python's linalg commands in HP Prime
Matrix Format [ [ row ], [ row ], … [ row ] ]
linspace(start, stop, number of points desired + 1) arange(start, stop, step size); default step size: 1; returns a 1 row array from start to stop using step size identity(n): returns an identity matrix as n x n transpose(matrix): transpose of a matrix inv(matrix): inverse of a matrix shape(matrix): returns the dimensions of the matrix in an ordered pair (row, columns) rref(matrix): row reduced echelon form of a matrix det(matrix): determinant of a square matrix peval(array of coefficients, x): polynomial evaluation (order is from high to low), can take complex arguments horner(array of coefficients, x): polynomial evaluation using Horner’s method pceoff(array of roots): returns an array representing a polynomial’s coefficients, can take complex arguments proot(array of coefficients): returns an array of roots, can take complex arguments add(array, array) or add(matrix, matrix): addition element by element sub(array, array) or sub(matrix, matrix): subtraction element by element dot(array, array): dot product cross(array, array): cross product imag(complex number): imaginary part – works on arrays and matrices real(complex number): real part – works on arrays and matrices I believe that fft and ifft have to do with fast fourier transforms.
