Found inside – We must remember that the conv ( p, q ) function is used with numeric expressions only, that is, polynomial coefficients. This MATLAB function returns the hyperbolic cosine function of X. Use the syms function to create a symbolic variable x and automatically assign it to a MATLAB variable x. precision using variable-precision arithmetic. Symbolic Math Toolbox™ includes operations and functions for symbolic math expressions that parallel MATLAB functionality for numeric values. Also, matlabFunction can create a file that accepts numeric arguments and evaluates the symbolic expression applied to the arguments. the number of rises and drops) that occur over a period of time. Found inside – Using MATLAB George Lindfield, John Penny. I want to solve the function passing the numeric matrix which replaces the symbolic matrix and provides a numeric answer. This MATLAB function returns the hyperbolic secant function of X.

Outdated Answers: accepted answer is now unpinned on Stack Overflow, How to simplify a symbolic and numeric mixed expression in Matlab, Vector inputs when converting symbolic expression to function handler, Factorise symbolic expression (square of a sum) in MATLAB, How to parse a symbolic expression in Matlab. Because symbolic variables are assumed to be complex by default, the result does not simplify to x^2. You want (and have, as shown in your question) an analytical expression for the second derivative. Found inside – There are many different commands and ways to create symbolic variables and functions within MATLAB. For kroneckerDelta with numeric inputs, use the eq function instead.
