string conversion to string string(x) [out, in, text] = string(x) x a boolean, complex, real, integer, polynomial matrix, an implicit size, a library or a function. 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 []. 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:$) part length quote evstr execstr strsubst strcat strindex sci2exp format 5.4.0 implicit size type managed as input argument.
