ncl使用双线性插值出错误，请教大家怎么解决！

木森林

begin

fi = addfile("E:/ep/epz.JRA55.nc", "r")
level = fi ->level
lat = fi ->lat
epz = fi ->epz

fo = addfile("E:/ep/epz.MIROC6.nc", "r")
LAT = fo ->lat
LEVEL = fo ->level

epz_1 = linint2_Wrap(level, lat, epz, True, LEVEL, LAT, 0)
printVarSummary(epz_1)

end

就显示这样的错误：
fatal:linint2: The rightmost dimensions of fi must be nyi x nxi, where nyi and nxi are the lengths of yi and xi respectively
