WebNov 12, 2012 · A partial derivative can also be performed in Matlab. A partial derivative is defined as a derivative of a multivariable function with respect to one variable, with all other variables treated as constants. Let’s generate a new equation based on x, y, and z: g (x,y,z) = x*y^2 – sin (z). WebThis function in MATLAB computes the numerical solution of PDE with the help of output of pdepe.

Webdiff (f,t) calculates the partial derivative . The result is ans = s*cos (s*t) To differentiate f with respect to the variable s , enter diff (f,s) which returns: ans = t*cos (s*t) If you do not specify a variable to differentiate with respect to, MATLAB chooses a default variable.
