Code Analyzer has detected a call to inv in a multiplication
operation.
For solving a system of linear equations, the inverse of a matrix is primarily
of theoretical value. Never use the inverse of a matrix to solve a linear system
Ax=b with x=inv(A)*b, because it is
slow and inaccurate.
Instead of multiplying by the inverse, use matrix right division
(/) or matrix left division (\). That is:
Replace inv(A)*b with
A\b
Replace b*inv(A) with
b/A
In longer expressions, parentheses might be necessary to preserve the order of
operations. For example, replace A*inv(B)*C with
A*(B\C).
Frequently, an application needs to solve a series of related linear systems
Ax=b, where A does not change, but
b does. In this case, use lu, chol, or qr instead of
inv,
depending on the matrix type.
