I have been running the submission using snopt matlab but it is showing the error "Undefined function or method 'snopt' for input arguments of type 'double'"
Undefined function or method 'julian' for input arguments of type 'double'.
Error in ==> readdata at 110
jdate0 = julian(month, day, year);
Error in ==> deorbit_snopt at 64
[fid, ta_lower, ta_upper] = readdata(filename);
Please help me out on the issue.
