How to find time derivative of a variable in a NetCDF File?

I am having a NetCDF file which has temperature as one of its variable and time as the other. I want to calculate partial derivative of Temperature w.r.t time to plot it with time. How can we execute this in MATLAB?

Read the variables into MATLAB from netCDF file using ncread. Let T be your temperature and t be you time variables. To get derivative of T w.r.t t use:

iwant = gradient(T)./gradient(t);

or

iwant = diff(T)./diff(t) ;

I go for gradient, because this will not reduce the size of variable.
