nancumsum
nancumsum: Cumulative sum of a matrix, with user-specified treatment of NaNs.
Computes the cumulative sum of matrix A along dimension DIM, allowing the user to replace NaNs with zeros, to skip over them, or to reset on NaNs, maintaining NaNs as placeholders.
USAGE: B = nancumsum(A, DIM, NMODE)
ARGUMENTS:
A: Input matrix.
B: Output cumulative sum matrix, treating NaNs as determined by nmode.
DIM: B = nancumsum(A, DIM) returns the nan-cumulative sum of the elements
along the dimension of A specified by scalar DIM. For example,nancumsum(A,1) works down the columns, nancumsum(A,2) works across the rows. If DIM is not specified, it defaults to the first non-singleton dimension of A.
NMODE: specifies how NaNs should be treated. Acceptable values are:
1: REPLACE NaNs with zeros (default).
2: MAINTAIN NaNs as position holders in B. (Skip NaNs without reset.)
3: RESET sum on NaNs, replacing NaNs with zeros.
4: RESET sum on NaNs, maintaining NaNs as position holders.

(nancumprod is available from the FEX. Other nan* may require Toolboxes)
