logreport - Quantization report

Syntax

logreport(a) logreport(a, b, ...)

Description

logreport(a) displays the minlog, maxlog, lowerbound, upperbound, noverflows, and nunderflows for the fi object a.

logreport(a, b, ...) displays the report for each fi object a, b, ... .

Examples

The following example produces a logreport for fi objects a and b:

fipref('LoggingMode','On');
a = fi(pi);
b = fi(randn(10),1,8,7);

Warning: 27 overflows occurred in the fi assignment operation.
Warning: 1 underflow occurred in the fi assignment operation.
