Usage
cdo_addtrend(ifile1, ifile2, ifile3, equal = NULL, ofile = NULL)
cdo_subtrend(ifile1, ifile2, ifile3, equal = NULL, ofile = NULL)
Arguments
ifile1 , ifile2 , ifile3 |
Strings with the path to the input files. |
equal |
BOOL - Set to false for unequal distributed timesteps (default: true) |
ofile |
String with the path to the output file. |
Details
addtrend Add trend It is o(t,x) = i_1(t,x) + (i_2(1,x) + i_3(1,x)*t) where t is the timesteps. subtrend Subtract trend It is o(t,x) = i_1(t,x) - (i_2(1,x) + i_3(1,x)*t) where t is the timesteps.
Value
Operators that output one or more files return a character vector to the output files.
Operators that output an indefinite number of files return a string with the basename of the files.
