string

Arguments

x

a boolean, complex, real, integer, polynomial matrix, an implicit size, a library or a function.

Description

The string function converts a matrix x into a matrix of strings.

If x is a function [out, in, text] = string(x) returns three vectors of strings: out is the vector of output variables, in is the vector of input variables, and text is the (column) vector of the source code of the function.

If x is a lib variable (library), text is a character string column vector. The first element contains the path of library file and the other the name of functions it defines.

Character strings are defined as 'string' (between quotes) or "string" (between doublequotes); matrices of strings are defined as usual constant matrices.

Concatenation of strings is made by the + operation.

For complex, real, integer, polynomial matrix string output is managed by format function (see examples).

Note that string([]) returns [].

Examples

string(rand(2, 2))

deff("y = mymacro(x)", "y = x + 1")
[out, in, text] = string(mymacro)
x = 123.356;
disp("Result is " + string(x));

disp("/" + string(~%t) + "/");
disp("/" + string(%i+1) + "/");
disp("/" + string(int16(-123)) + "/");
disp("/" + string(1 + %s + %s^3) + "/");

string(corelib)

v = format();
disp(string(%pi))
format(24);
disp(string(%pi))
format(v(2))

string(1:4:$)
