Iff cannot be factored over the rational numbers, the result is fitself. factor If fis a polynomial with rational coefficients, the statement > factor(f) expresses f as a product of polynomials of lower degree with rational coefficients.

A second argument can specify the variable in which to collect terms if there is more than one candidate. collect The statement > collect(t) views f as a polynomial in its symbolic variable, say x, and collects all the coefficients with the same power of x. pretty Here are three different symbolic expressions. Then enter >f=a*x^2+b*x+c Simplifications 1. Creating Symbolic Variables And Expressions The ' sym" command lets you construct symbolic variables and expressions.

Facility Covers Calculus Differentiation, integration, limits, summation, and Taylor series Linear Algebra Inverses, determinants, eigenvalues, singular value decomposition, and canonical forms of symbolic matrices Simplification Methods of simplifying algebraic expressions Solution of Symbolic and numerical solutions to algebraic and Equations differential equations Special Special functions of classical applied mathematics Mathematical Functions Variable-Precision Numerical evaluation of mathematical expressions Arithmetic to any specified accuracy Transforms Fourier, Laplace, 2-transform, and corresponding inverse transforms Why we need Symbolic Math toolbox? Since the control system toolbox cannot find the direct laplace transforms in system modeling, thus we need to have another toolbox that can not only find the transforms but also assist us solving simultaneous equations and other mathematical problems in controls.

These toolboxes supplement MATLAB numeric and graphical facilities with several other types of mathematical computation, which are summarized in following table.

And you're doing this matrix which you've already defined as a eight times and then you were multiplying it by these values X, y and Z. Close your bracket because you're done the semi colon to start a new line. And then semi colon to let matt love know you're going to the next line to negative 37 semi colon 1 -6 1. We're not putting what it equals because we're checking that. So when you're talking about matrix multiplication you just need the coefficients. If you check it on the very next line, X, y and Z are already defined. That tells matt lab look for X, Y and Z as your symbols put this in and you get a quantity for exa quantity for Y and quantity for Z. Set it up, set up the third line and then comma, make sure you put X, Y and C at the end. So don't forget those apostrophes same thing.

You list the first system three X plus four way plus five, Z is equal to two and you need that first bit in apostrophes that lets matt lab know, hey this is your first wine comma, your second line.

So solve is the command to tell matt lab, solve this system. That means this is what we're looking for. So first we set it up as a matrix X comma, Y, comma Z. Make sure you have the symbolic math toolbox because it is necessary to solve this system of equations symbolically.
