isfinite

isfinite determines whether the given number is finite.

r = isfinite(m)

Return Value

r is TRUE (1), if m is finit, i.e. if m != INF and m != -INF and m is not a NaN.

Parameters

m

is a real scalar or real matrix.

Example

1/0
    1.#INF
0/0
    -1.#IND
isfinite(1/0)
    0.0000
isfinite(0/0)
    0.0000
isnan(1/0)
    0.0000
isnan(0/0)
    1.0000
isnan(0/0)
    1.0000
isnan(1e300*1e300)
    1.0000
isnan(-1e300*-1e300)
    1.0000
