Matlab selects axis limits based on the range of the plotted data. You can specify the limits manually using the axis command. Call axis with the new limits defined as a four-element vector. axis([xmin,xmax,ymin,ymax]) By default, Matlab displays graphs in rectangular axes that have the same aspect ratio as the figure window.

Step 1 is to tell MATLAB which polynomial you want to solve. This is done by typing the following statement at the prompt in the command window: >> p = [1 2 5 12 5 -15] With this expression, you have given MATLAB sufficient information about the polynomial that you want to solve. In step 2, you tell MATLAB to solve for the roots of the polynomial.

In MatLab®, polynomials are represented by a vector composed of the coefficients. Thusly, b. Evaluate. A polynomial is evaluated using the command polyval. If p is the vector of coefficients and x is the argument, polyval(p,x) or y=polyval(p,x) The roots command gives the roots of a polynomial, as elements of a vector. r=roots(p)

The polynomial is continuous and differentiable at all orders and therefore suggests itself as a plausible representation of the protein curve). In MATLAB we can obtain the roots of the polynomial by the “roots” command. For example, consider the polynomial below: The “roots” command finds the zeroes of the polynomial >> roots([5 1 0 2 ...

Polynomials Polynomials in Matlab are represented in the same manner as vectors (a 1 X N matrix). For instance if we used a from above to form a polynomial meaning: f = a(1)*x^2 + a(2)*x + a(3) Notice the use of the notation a(), this allows you to return a value of vector with location , also Matlab indices ALWAYS start with 1.

The approximation improves as one adds more terms to the polynomial (order), or moves closer to the point about which the expansion was made. This can be illustrated by: >> ezplot(Tay_expx), hold on, ezplot(exp(x)), hold off. Summations: MATLAB’s symbolic engine is also capable of doing symbolic summations, even those with infinitely many terms!
