[SciPy-user] numarray.dot

[Colin J. Williams]

This function appears to take only partial account of imaginary data, 
see the
second exeution below..

I would have expected a complex element type in a ComplexArray instance.
or a message that this type of input cannot be handled.

print 'version:', _sys.version

import numarray as N
z= N.dot([1, 2], [[3], [4]])
print 'z, type(z), z[0], z.type():', z, type(z), z[0], z.type()

z= N.dot([1, 2], [[3j], [4]])
print 'z, type(z), z[0], z.type():', z, type(z), z[0], z.type()

Results:
