isbanded

Determine if matrix is within specific bandwidth.

Syntax

• tf = isbanded(A, lower, upper)

Input argument

• A - Input matrix

• lower, upper - lower bandwidth,

Output argument

• tf - logical

Description

tf = isbanded(A, lower, upper) returns true if matrix A is within the specified lower bandwidth, lower, and upper bandwidth, upper.

Example

M = [1 0 0 0 0; 2 1 0 0 0; 3 2 1 0 0]
TF = isbanded(M, 2, 0)
TF = isbanded(M, 2, 1)
