Input Matrix can be a rectangular matrix when norm type is 2-norm. If norm type is not 2-norm, Input Matrix must be a square matrix. | ||||||||

norm type indicates what type of norm is used to compute the condition number.
Refer to the Complex Matrix Norm VI for a definition of a matrix norm.

condition number is the calculated condition number for a given norm. For the 2-norm the condition number is the ratio of the largest, singular value of Input Matrix to the smallest, singular value of Input Matrix. | ||||||||

error returns any error or warning condition from the VI. |
Condition number defines c as
is the norm of Input Matrix A. Different values of p define the different types of norms, therefore p defines different types of computations of condition numbers.
The condition number of a matrix measures the sensitivity of the solution of a system of linear equations to errors in the data. It gives an indication of the accuracy of the results from the matrix inversion and linear equation solutions.
