![]() It also does all the standard integration, differentiation, and even Taylor’s series expansion □ and has a lot of applications. ![]() Note the usage of the function solve() which is typically used to solve for variable given a polynomial equation. Rxx = Īnd you have the possible solutions for this variable z. What symbolic math toolbox allows you to do is, define a variable – say z. However, now consider a 20×20 matrix □ Its terrible to compute its determinant, and then there is still an equation to solve. Its a simple quadratic equation, and it can be solved for. You want to obtain a value for this, such that the determinant of the matrix goes to 0. Consider a simple 3×3 symmetric matrix, whose non-diagonal corners are equal, and unknown. The example where I used it is like this. ![]() This is the Symbolic Math Toolbox, and its uses are numerous.Īlthough I am sure it requires a lot of development, specially compatibility of integrating with other data types that Matlab supports, for starters, it seems like a really nice feature. Maybe higher and more complex graphing calculators can do indefinite stuff too! However, I just found this very interesting ability to use a math symbol, typically x, so far known to exist only in Mathematica. Your scientific calculator now does definite integration, differentiation, etc.
