comparing the empirical spectral density and the predicted (theoretical) self-adjoint pseudospecturum of non-Hermitian Kronecker random matrices simulating the empirical spectral density of ...

Expressions like the following are called polynomials in one variable. 0, -5, 7 etc. are examples of constant polynomials. The constant polynomial 0 is also the zero polynomial. Others like 7x + 9 is ...

# Define a function to add two polynomials. def add(p, q): return [pp + qq for pp, qq in zip_longest(p, q, fillvalue=0)] # Define a function to subtract two polynomials. def subtract(p, q): return [pp ...

Abstract: We consider analytical modeling of the anterior corneal surface with a set of orthogonal basis functions that are a product of radial polynomials and angular functions. Several candidate ...
