Use the diff function to approximate partial derivatives with the syntax Y = diff (f)/h, where f is a vector of function values evaluated over some domain, X, and h is an appropriate step size. For example, the first derivative of sin (x) with respect to x is cos (x), and the second derivative with respect to x is -sin (x).

As an example, create a rational expression (i.e., a fraction where the numerator and denominator are polynomial expressions). f = (3*x^3 + 17*x^2 + 6*x + 1)/ (2*x^3 - x + 3) f =. 3 x 3 + 17 x 2 + 6 x + 1 2 x 3 - x + 3. Plotting this expression shows that the expression has horizontal and vertical asymptotes, a local minimum between -1 and 0 ...

Numerical Integration and Differentiation. Numerical integration functions can approximate the value of an integral whether or not the functional expression is known: When you know how to evaluate the function, you can use integral to calculate integrals with specified bounds. To integrate an array of data where the underlying equation is ...

To determine the default variable that MATLAB differentiates with respect to, use symvar: symvar (f, 1) ans = t. Calculate the second derivative of f with respect to t: diff (f, t, 2) This command returns. ans = -s^2*sin (s*t) Note that diff (f, 2) returns the same answer because t …

where t is the current simulation time and T p r e v i o u s is the time of the last output time of the simulation. The latter is the same as the time of the last major time step. The Derivative block output might be sensitive to the dynamics of the entire model. The accuracy of the output signal depends on the size of the time steps taken in the simulation.

Numerical Integration and Differentiation. When you know how to evaluate the function, you can use integral to calculate integrals with specified bounds. To integrate an array of data where the underlying equation is unknown, you can use trapz, which performs trapezoidal integration using the data points to form a series of trapezoids with ...

Note. Use these syntaxes for sfit objects. [fx, fy] = differentiate (FO, X, Y) differentiates the surface FO at the points specified by X and Y and returns the result in fx and fy. FO is a surface fit ( sfit) object generated by the fit function. X and Y must be double-precision arrays and the same size and shape as each other.
