SFLOP simulates a floating point operation
x op y where op = +, -, *, /
In chopping or rounding arithmetic using an
m digit mantissa, base 10, and an unrestricted
exponent range. (sflop: Simulate FLOating Point
operation.) For more details on the how the floating
point representation of a number is computed see
the function sfl.
FFTGUI Demonstration of Finite Fourier Transform.
FFTGUI(y) plots real(y), imag(y), real(fft(y)) and imag(fft(y)).
FFTGUI, without any arguments, uses y = zeros(1,32).
When any point is moved with the mouse, the other plots respond.
