C4LIB <br> A Single Precision Complex Arithmetic Utility Library
</h1>
<hr>
<p>
<b>C4LIB</b>
is a MATLAB library which
implements certain
elementary functions for "C4" or
single precision complex variables.
</p>
<p>
The symbol "C4" is used to suggest a single precision complex
variable. Here the 4 indicates that the underlying pair of
real numbers each use 4 bytes of storage.
</p>
<p>
C4LIB contains routines that operate on scalars, vectors or
doubly dimensioned arrays of C4's. A vector of C4's is denoted
a C4VEC, and a doubly dimensioned array is a C4MAT.
