Because so many of the brain's higher centers sprouted from or extended the scope of the limbic area, the emotional brain plays a crucial role in neural architecture.

any(x) returns the scalar 1 (true) if any element of x is non-zero (true)

all(x) returns the scalar 1 if all the elements of x are non-zero

exist(’a’) returns 1 if a is a workspace variable. For other possible return values see help. Note that a must be enclosed in apostrophes

find(x) returns a vector containing the subscripts of the non-zero (true) ele- ments of x

a = a( find(a) ) removes all the zero elements from a!

Another use of find is in finding the subscripts of the largest (or smallest) elements in a vector, when there is more than one.

isempty(x) returns 1 if x is an empty array and 0 otherwise. An empty array has a size of 0-by-0

isinf(x) returns 1s for the elements of x which are +Inf or −Inf, and 0s otherwise

isnan(x) returns 1s where the elements of x are NaN and 0s otherwise. This function may be used to remove NaNs from a set of data.

if a ~= b % wrong wrong wrong!!! statement end However this will not work, since statement will only execute if each of the cor- responding elements of a and b differ. This is where any comes in: if any(a ~= b) % right right right!!! statement end
