I am running version R2011b. I am trying to re-grid data from an irregular lat/lon grid to a regular lat/lon grid. My input arrays X, Y, Z are dimensioned (349,277). My target grid is dimensioned (96,60). When griddata is called I get an error in DelaunayTri as "Parameter must be a 'double matrix'". I have used griddata in the past with no problems and I can not figure out what this error message means. Any suggestions?

What is the class of the variables?
class(X)
If it's not double, convert it to double using double()
