<br />
The UnaryOperations can also be called through an interface. The subroutine which is called is determined by the class of the arguments.<br />
<br />
<br />
The general calling syntax of the subroutine is (see below for further details): <br />
<br />
<pre>call IXFoperation(result, object, status)</pre><br />
<br />
<br />
==Operations==<br />
<br />
<br />
*log - takes the natural logarithm of an object<br />
*exp - takes the exponential of an object<br />
*sin - takes the sine of an object<br />
*cos - takes the cosine of an object<br />
*tan - takes the tangent of an object<br />
*sinh - takes the hyperbolic sine of an object<br />
*cosh - takes the hyperbolic cosine of an object<br />
*tanh - takes the hyperbolic tangent of an object<br />
<br />
<br />
==Valid Classes==<br />
<br />
<br />
Classes for which operations are vaild and overloaded:<br />
<br />
<br />
*[[IXTdatum]]<br />
*[[IXTdatum_array]]<br />
*[[IXTdataset_1d]]<br />
*[[IXTdataset_2d]]<br />
<br />
<br />
<br />
==F90 syntax==<br />
<br />
<br />
<pre>use IXMclass<br />
type(IXTclass)::object,result<br />
<br />
type(IXTstatus)::status<br />
<br />
call IXFoperation(result,object,status)</pre><br />
<br />
<br />
For example with operation=sinh class=dataset_1d<br />
<br />
<br />
<pre>use IXMdataset_1d<br />
<br />
type(IXTdataset_1d):: w1, wres<br />
type(IXTstatus)::status<br />
<br />
call IXFsinh(wres,w1,status)</pre></div>Dean Whittaker
