Toolbox Misc

A bunch of useful functions.

Description

toolbox_misc - a bunch of useful functions.
 
    List of functions:
        - keep_above - keep only the coefficients above threshold T, set the rest to zero.
        - keep_biggest - keep only the n biggest coef, set the rest to zero.
        - l2error - compute the decreasing of the L^2 error from orthogonal coefficients.
        - norme - just the L^2 norm of a vector/matrix
        - plot_curve - plot a 2d curve.
        - plot_scattered - plot 2D scattered data using triangulation.
        - rescale - rescale data in [a,b]
        - rev_sort_abs - sort by decreasing order of absolute value
        - reverse - flip a vector.
        - reverse_permutation - compute the inverse of a permuation
        - save_image - save current graphic with given base name
        - verbose - display a string.
        - build_vandermonde_matrix - build the Vandermonde matrix associdated to the sampling x.
        - clamp - clamp a value
        - mmax - maximum entry from a matrix
        - poly_derivate - compute the derivative of the polynomial
        - poly_root - find the roots of a polynomial
        - poly_val - evaluate a polynomial
        - remove_doublon - remove doublon from a vector.

[teuteu teuteu]

ça a l'air pas mal ta ptite toolbox
mon vieux gab'

[Duane Hanselman]

This collection of functions appear to duplicate what is inherently available in MATLAB. Those functions that are not in MATLAB can be resubmitted as individual files.

[Con Fused]

What's the need of this toolbox?

[Jimmy Banker]

i need poly_root to work, it is throwing an error at me

Error in ==> poly_root at 14
if size(P,1)==1 && size(P,2)==1

idk how to fix it
