Check whether symbolic array elements are NaN
s
NaN
sUsing isnan
, determine which
elements of this symbolic matrix are NaN
s:
isnan(sym([pi NaN Inf; 1 + i Inf + i NaN + i]))
ans = 2×3 logical array 0 1 0 0 0 1
For any A
, exactly one of the
three quantities isfinite(A)
, isinf(A)
,
or isnan(A)
is 1
for each element.
Symbolic expressions and functions containing NaN
evaluate
to NaN
. For example, sym(NaN + i)
returns
symbolic NaN
.
