Singular Manual: LRschubmult

| #### D.15.9.6 LRschubmult Procedure from library `lrcalc.lib` (see lrcalc_lib). Usage: LRschubmult(x, y); x, y lists of integers Return: list of lists Purpose: computes the expantion of a product of two Schubert polynomials in the basis of Schubert polynomials Note: Example:
    LIB "lrcalc.lib";
    // Compute the expantion of a square of the Schubert polynomial
    // corresponding to  (1 3 2) in the basis of Schubert polynomials
    list x = 1, 3, 2;
    LRschubmult(x, x);
