====CCONV - real/complex spectrum conversions====

The format of the input <var>X</var> and the desired format of the output <var>Y</var> are defined by the two inputs <var>XTYPE</var> and <var>YTYPE</var>. The input <var>C</var> is used as factor or dB offset. All combinations of input and output types are possible. If a real spectrum (Power, Linear, Logarithmic) is converted to a complex spectrum, the imaginary part is always set to zero for all components. If the input is a complex spectrum and the output is a real spectrum, the output vector length is the half of the input vector length (and vice versa). If the input is a single number, the output is a vector with two entries (if <var>YTYPE</var> = <code>0</code>) or a single number. If <var>XTYPE</var> is set to <code>COMPLEX</code> the input <var>C</var> can also be a vector. In this case <var>X</var> is the real and <var>C</var> the imaginary data. If <var>XTYPE</var> is <code>COMPLEX</code> and <var>C</var> is a number then <var>X</var> is interpreted as alternating real and imaginary data.

=====Usage:=====

<code>CCONV <var>X</var> <var>C</var> <var>XTYPE</var> <var>YTYPE</var></code>

=====Inputs:=====

;<var>X</var>

:The input data (spectrum).

;<var>C</var>

:A factor or vector.

;<var>XTYPE</var>

:The type of input spectrum. The following values are supported:

:<code>COMPLEX</code>|<code>0</code> - the input is a complex spectrum (re/im value pairs).
<code>POWER</code>|<code>1</code> - the input is a power spectrum.
<code>LINEAR</code>|<code>2</code> - the input is a linear magnitude spectrum.
<code>LOGARITHMIC</code>|<code>3</code> - the input is a logarithmic spectrum (dB).

;<var>YTYPE</var>

:The type of output spectrum. See <var>XTYPE</var> for details.

=====Outputs:=====

;<var>Y</var>

:The output data (converted spectrum).

=====Function:=====
