<h1><a class="anchor" id="Usage"></a>
Usage</h1>
<p>Constructs an inline function object. The syntax for its use is either </p>
<pre class="fragment"> y = inline(expr)
</pre><p> which uses the <code>symvar</code> function to identify the variables in the expression, or the explicit form </p>
<pre class="fragment"> y = inline(expr,var1,var2,...,varn)
</pre><p> 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. </p>
<h1><a class="anchor" id="Example"></a>
Example</h1>
<p>Here we construct an inline expression using the autodetection of <code>symvar</code></p>
<pre class="fragment">--> a = inline('x^2')
a =
inline function object
f(x) = x^2
--> a(3)
ans =
9
--> a(i)
ans =
-1.0000 + 0.0000i
</pre><p>In this case, we have multiple arguments (again, autodetected)</p>
<pre class="fragment">--> a = inline('x+y-cos(x+y)')
a =
inline function object
f(x,y) = x+y-cos(x+y)
--> a(pi,-pi)
ans =
-1
</pre><p>In this form, we specify which arguments we want to use (thereby also specifying the order of the arguments</p>
<pre class="fragment">--> 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
</pre><p>Inline objects can also be used with <code>feval</code></p>
<pre class="fragment">--> a = inline('cos(t)')
a =
inline function object
f(t) = cos(t)
--> feval(a,pi/2)
ans =
6.1232e-17
