plot a polynomial with z^(5/2) exponent in matlab

To plot a polynomial with z^(5/2) exponent in MATLAB, you can first define a symbolic variable 'z', create a polynomial expression using 'z' with the desired exponent, and then plot the expression over the desired range of values using the 'fplot' function.

Here's an example code that creates a polynomial expression, sets the range of values to be plotted, and then generates the plot:

main.m
syms z            % Define symbolic variable 'z'
p = z^(5/2) + 3*z^2 + 2;   % Define the polynomial expression with desired exponent
fplot(p, [0 5]);   % Plot the polynomial over the range [0, 5]
title('Polynomial with z^{5/2} Exponent')   % Set plot title
xlabel('z')    % Set x-axis label
ylabel('f(z)')    % Set y-axis label

This will generate a plot of the polynomial function with 'z' values from 0 to 5 on the x-axis and corresponding function values on the y-axis.

Note that the 'fplot' function requires the symbolic toolbox, so you may need to have that installed to run this code.
