INLINE Construct Inline Function

Section: Function Related Functions

Usage

Constructs an inline function object. The syntax for its use is either 
   y = inline(expr)

which uses the symvar function to identify the variables in the expression, or the explicit form 

   y = inline(expr,var1,var2,...,varn)

where the variables are explicitly given. Note that inline functions are only partially supported in FreeMat. If you need features of the inline function that are not currently implemented, please file a feature request at the FreeMat website.

Example

Here we construct an inline expression using the autodetection of symvar 
--> a = inline('x^2')

a = 
  inline function object
  f(x) = x^2
--> a(3)

ans = 
 9 

--> a(i)

ans = 
  -1.0000 +  0.0000i

In this case, we have multiple arguments (again, autodetected) 

--> a = inline('x+y-cos(x+y)')

a = 
  inline function object
  f(x,y) = x+y-cos(x+y)
--> a(pi,-pi)

ans = 
 -1

In this form, we specify which arguments we want to use (thereby also specifying the order of the arguments 

--> a = inline('x+t-sin(x)','x','t')

a = 
  inline function object
  f(x,t) = x+t-sin(x)
--> a(0.5,1)

ans = 
    1.0206

Inline objects can also be used with feval 

--> a = inline('cos(t)')

a = 
  inline function object
  f(t) = cos(t)
--> feval(a,pi/2)

ans =
