Every week we get Down & Dirty, in which we break down our favorite unique seasonal fruits, vegetables, and more. Today: we're talking about fiddlehead ferns -- learn what to look for, how to prep them, and get ideas for safely enjoying them in meals all week long.

We can define symbolic functions using the sym command and syms command. Here is an example of creating a symbolic function for (a*X^2) + (b*x) + c: >> syms a b c x % define symbolic math variables >> f = sym('a*x^2 + b*x + c'); From now on we can use the f symbol to represent the given function. Evaluation of Symbolic Expressions The keyfunction subs (which stands for substitute) is used to replace symbolic variables with either new symbolic variables or with actual values. The syntax for the function is: subs( symbolic_function, list_of_symbols, list_of_values). Here is an example: >> f = sym('a*x^2 + b*x + c'); >> subs(f,x,5) ans = 25 * a + 5 * b + c
