tostring

Convert fi, fimath, numerictype, or quantizer object to string

Description

example

s = tostring(a) converts fi object a to a character vector s such that eval(s) would create a fi object with the same properties as a.

example

s = tostring(F) converts fimath object F to a character vector s such that eval(s) would create a fimath object with the same properties as F.

example

s = tostring(T) converts numerictype object T to a character vector s such that eval(s) would create a numerictype object with the same properties as T.

example

s = tostring(q) converts quantizer object q to a character vector s such that eval(s) would create a quantizer object with the same properties as q.
