The elementary functions are those which act on all the signal data contained in an [[IXTdataset_1d]] or [[IXTdataset_2d]].

These functions are

<pre>>> wnew = log(w)
>> wnew = exp(w)
>> wnew = sin(w)
>> wnew = cos(w)
>> wnew = tan(w)
>> wnew = sinh(w)
>> wnew = cosh(w)
>> wnew = tanh(w)</pre>

where w is an [[IXTdataset_1d]] or [[IXTdataset_2d]]. Here the operation is performed on every signal value in the dataset.

==Arrays of Datasets==

If an array is given, then the operation is performed on each member of the array in turn.

''' example: '''

>> '''wnew''' = exp('''w''')

will be handled as

'''wnew(i)'''.signal(j) = exp('''w(i)'''.signal(j))
