char - Convert symbolic objects to strings

Syntax

char(A) char(A, d)

Description

char(A) converts a symbolic scalar or a symbolic array to a string.

char(A, d) converts a symbolic scalar or array to a string. For symbolic arrays, the second parameter specifies the form of the resulting string. For symbolic scalars, this parameter does not affect the result. d will be removed in a future release.

Inputs

`A`	A symbolic scalar or a symbolic array

d

d will be removed in a future release.

A number that specifies the format of the resulting string. For symbolic arrays:

char (A, 1) results in matrix([...])

char(A, 2) results in matrix([[...],[...]])

char(A, d) for all other values of the parameter d results in array([1..m, 1..n, 1..p], [(1,1,1) = xxx,...,(m,n,p ) = xxx])

Examples

Convert symbolic expressions to strings, and then concatenate the strings:

syms x;
y = char(x^3 + x^2 + 2*x - 1);
name = [y, ' presents a polynomial expression']

The result is:

name =
x^3 + x^2 + 2*x - 1 presents a polynomial expression

Convert a symbolic matrix to a string:

A = sym(hilb(3))
char(A)
