nan

Array of not-a-numbers (NaN)

Usages

nan

• It returns not-a-number.

nan(n)

• n should be real non-negative integer scalar.
• It returns an n-by-n matrix containing all not-a-numbers.
• It does not accept nan nor ±inf as its input argument.

nan(s1,s2,...,sn)

• s1, s2, ..., sn should be real non-negative integer scalars.
• It does not accept nan nor ±inf as its argument.
• It returns an array of size [s1 s2 ... sn] that contains all not-a-numbers.

nan(sizeVec)

• It returns an array of size specified by the vector sizeVec.
• The vector sizeVec should contain real non-negative integers, not equal to neither nan nor ±inf.
• The array contains all not-a-numbers.
