Syntax
Description
Examples
Determine If All Vector Elements Are Finite
Create a row vector and determine if all elements are finite.
A = 1./[-2 -1 1e-23 0.1]
A = 1×4
1023 ×
-0.0000 -0.0000 1.0000 0.0000
TF = allfinite(A)
TF = logical
1
Create another row vector and determine if all elements are finite.
B = 0./[-2 -1 0 0.1]
B = 1×4
0 0 NaN 0
TF = allfinite(B)
TF = logical
0
Determine If All Matrix Elements Are Finite
Create a matrix and determine if all elements are finite.
A = [0 0 3;0 0 3;0 0 NaN]
A = 3×3
0 0 3
0 0 3
0 0 NaN
TF = allfinite(A)
TF = logical
0
Determine If All Array Elements Are Finite
Create a 3-D array and determine if all elements are finite.
A(:,:,1) = [2 1; 3 5]; A(:,:,2) = [0 0; 0 Inf]; A(:,:,3) = [-2 9; 4 1]
A = A(:,:,1) = 2 1 3 5 A(:,:,2) = 0 0 0 Inf A(:,:,3) = -2 9 4 1
TF = allfinite(A)
TF = logical
0
Determine If All Complex Elements Are Finite
Create a vector of complex numbers. Determine if all elements are finite.
A = [2+3i 3/0+1i -2i]
A = 1×3 complex
2.0000 + 3.0000i Inf + 1.0000i 0.0000 - 2.0000i
TF = allfinite(A)
TF = logical
0
allfinite(A)
returns 0
because the second element of A
has a real part that is infinite.
