ezplot (f) plots a symbolic expression, equation, or function f. By default, ezplot plots a univariate expression or function over the range [–2π 2π] or over a subinterval of this range. If f is an equation or function of two variables, the default range for both variables is [–2π 2π] or over a subinterval of this range.
The plot now detects the step function and shows that by increasing MeshDensity you increased the plot's resolution. syms x stepFn = rectangularPulse(2.1, 2.15, x); subplot(2,1,1) fplot(stepFn); title( 'Default MeshDensity = 23' ) subplot(2,1,2) fplot(stepFn, 'MeshDensity' ,39); title( 'Increased MeshDensity = 39' )
Create Plots Plot with Symbolic Plotting Functions. MATLAB ® provides many techniques for plotting numerical data. Graphical capabilities of MATLAB include plotting tools, standard plotting functions, graphic manipulation and data exploration tools, and tools for printing and exporting graphics to standard formats.

A = sym (hilb (3)); B = sym ( [1 1/2 5; 1/2 2 1/4; 1/3 1/8 1/5]); isAlways (A == B) ans = 3×3 logical array 1 1 0 1 0 1 1 0 1. Compare a matrix and a scalar. The == operator expands the scalar into a matrix of the same dimensions as the input matrix.
If you do not specify any variable, MATLAB ... fplot to create 2-D plots of symbolic expressions, equations, or functions in Cartesian coordinates. fplot3 to create 3-D parametric plots. ezpolar to create plots in polar coordinates. fsurf to create surface plots.
Plot a Function y = g ( x 0 , a ) with a as the Horizontal Axis ... Find the x 0 that minimizes a function g ( x , a ) by solving the differential equation d g ( ...
Re-evaluation on Zoom. When you zoom into a plot, fplot re-evaluates the plot automatically. This re-evaluation on zoom reveals hidden detail at smaller scales. Plot x^3*sin(1/x) for -2 < x < 2 and -0.02 < y < 0.02.Zoom in on the plot using zoom and redraw the plot using drawnow.Because of re-evaluation on zoom, fplot reveals smaller-scale detail. Repeat the zoom 6 times to view smaller …
Sep 28, 2017 · plot (t, subs (X,'t',t) ) Which is to say that if you use a symbolic variable in an expression and later assign a numeric value to the symbol, then the expressions that used the symbolic variable are not automatically updated to use the numeric value. The situation is exactly the same as if you had used. A = 1;
Plot the hyperbola described by the function f (x, y) = x 2-y 2-1 by first declaring the symbolic function f(x,y) using syms. The fimplicit function uses the default interval of [ - 5 , 5 ] for x and y .

Numerically Solve Equations. When the solve function cannot symbolically solve an equation, it tries to find a numeric solution using the vpasolve function. The vpasolve function returns the first solution found. Try solving the following equation. The solve function returns a numeric solution because it cannot find a symbolic solution.
