Description

deff can be used to define functions from sequences of instructions written in text strings. The resulting function object has the same properties of any other function defined in a text file and loaded with exec.

Quotes included in instructions given in strings must be doubled to be protected.

Examples

deff('x = myplus(y,z)', 'x = y+z')
myplus(1,%i)

deff('[y, z] = mymacro(x)', ['y = 3*x+1'; 'z = a*x + x.^2'])
a = 3;
[u, v] = mymacro(2)
--> deff('x = myplus(y,z)', 'x = y+z')
--> myplus(1,%i)
 ans  =
   1. + i

--> deff('[y, z] = mymacro(x)', ['y = 3*x+1'; 'z = a*x + x.^2'])
--> a = 3;
--> [u, v] = mymacro(2)
 v  =
   10.

 u  =
   7.
