If you use log(3), then MATLAB ® calculates log(3) with the double precision, and then converts the result to a symbolic number. We would like to show you a description here but the site won’t allow us. See syntax, examples, and names of symbolic objects. You can also use sym to create a symbolic scalar variable. See examples of calculus, linear algebra, differential equations, and more. The sym function also lets you define a symbolic matrix or vector without having to define its elements in advance. For example, syms f(x) [1 2] creates the symbolic array f(x) = [f1(x) f2(x)], the symbolic functions f1 and f2, and the symbolic scalar variable x in the MATLAB workspace. Use symbolic functions for differentiation, integration, solving ODEs, and other math operations. Create symbolic functions by using syms.
