By using the symbolic toolbox and diff() function the partial derivatives can be simplified as follows. I'm not sure if you'd like to solve ...

Here is a particular code. Can anyone please help me in taking the analytical (partial) derivative of the function 'F' along X (i.e., w.r.t. X) along Y ...

Solving Partial Differential Equations. In a partial differential equation (PDE), the function being solved for depends on several variables, and the differential equation can include partial derivatives taken with respect to each of the variables. Partial differential equations are useful for modelling waves, heat flow, fluid dispersion, and ...

Mar 20, 2014 · Partial Derivatives in Matlab. f ( x, y) = 9 - x 2 - y 2 . Let's use Matlab to draw the surface represented by the function f over the domain { ( x, y): - 2 ≤ x, y ≤ 2 }. We begin by creating a grid of ( x, y) pairs. When used in this form, Matlab uses the entries in the vector -2:.25:2 for both x and y.

The equation is valid for t > 0 due to the inconsistency in the boundary values at x = 0 for t = 0 and t > 0.Since the PDE has a closed-form series solution for u (x, t), you can calculate the emitter discharge current analytically as well as numerically, and compare the results.

Feb 11, 2013 · Thank you sir for your answers. Actually I need the analytical derivative of the function and the value of it at each point in the defined range. i.e. diff (F,X)=4*3^(1/2)*X; is giving me the analytical derivative of the function.
