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.
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 = 6.1230e-17
