betainc
Incomplete beta function
Syntax
I = betainc(X,Z,W)
I = betainc(X,Z,W,tail)
Description
I = betainc(X,Z,W)
computes
the incomplete beta function for corresponding elements of the arrays X
, Z
,
and W
. The elements of X
must
be in the closed interval [0,1]. The arrays Z
and W
must
be nonnegative and real. All arrays must be the same size, or any
of them can be scalar.
I = betainc(X,Z,W,tail)
specifies
the tail of the incomplete beta function. Choices are:
| Computes the integral from |
| Computes the integral from |
These functions are related as follows:
1-betainc(X,Z,W) = betainc(X,Z,W,'upper')
0
, it is more
accurate to use the 'upper'
option than to subtract the
'lower'
value from 1
