mat2str

Convert matrix to string

Syntax

str = mat2str(A)

str = mat2str(A, n)

str = mat2str(A, 'class')

str = mat2str(A, n, 'class')

Description

str = mat2str(A) converts fi object A to a string representation. The output is suitable for input to the eval function such that eval(str) produces the original fi object exactly.

str = mat2str(A, n) converts fi object A to a string representation using n bits of precision.

str = mat2str(A, 'class') creates a string representation with the name of the class of A included. This option ensures that the result of evaluating str will also contain the class information.

str = mat2str(A, n, 'class') uses n bits of precision and includes the class of A.

Examples

Convert fi Object to a String

Convert the fi object a to a string.

a = fi(pi);
str = mat2str(a)

str = 
'3.1416015625'

Convert fi Object to a String with Specified Precision

Convert the fi object a to a string using eight bits of precision.

a = fi(pi);
str = mat2str(a, 8)

str = 
'3.1416016'

Input Arguments

A — Input array

scalar | vector | matrix
