[H,theta,rho] = hough(BW) computes the Standard Hough Transform (SHT) of the binary image BW. The hough function is designed to detect lines. The function uses the parametric representation of a line: rho = …In particular, on remote Linux servers it is often best to run MATLAB from the command-line and not interactively. Once your MATLAB code is finished and tested, ...However, you can use the hold on command to combine multiple plots in the same axes. For example, plot two lines and a scatter plot. Then reset the hold state to off. x = linspace (0,10,50); y1 = sin (x); plot (x,y1) title ( 'Combine Plots' ) hold on y2 = sin (x/2); plot (x,y2) y3 = 2*sin (x); scatter (x,y3) hold off. When the hold state is on ...I see 4 lines. Anyway, extract the x and y coordinates that you want to fit a line to, then use polyfit: Theme. Copy. coefficients = polyfit (x, y, 1); % Now get the slope, which is the first coefficient in the array: slope = coefficients (1); 6 Comments. Show 5 …Method 2: use intersections () to find x-intercepts. This uses the intersections () function from the file exchange to find the (x,y) coordinates of the x-intercepts. Theme. Copy. x=linspace (-4,4); V= (x.^3/3)-4*x; [xInt,yInt] = intersections (x,V,x,zeros (size (V))); % ^^ ^^ There are your intercept coordinates.

Title with Variable Value. Include a variable value in the title text by using the num2str function to convert the value to text. You can use a similar approach to add variable values to axis labels or legend entries. Add a title with the value of sin ( π) / 2. k = sin (pi/2); title ( [ 'sin (\pi/2) = ' num2str (k)])Theme. Copy. y = C (1)*x + C (2)*x^2 + C (3)*x^3 + C (4)*x^4. That forces the curve to pass through zero, has a bump at the bottom end, etc. But it has a little tweak near the top. Theme. Copy. spl = spline (x,y); plot (x,y,'o',xint,ppval (spl,xint),'r-')

Plot two lines by specifying x and y as matrices. Use line to plot columns of y versus columns of x as separate lines. x = linspace (0,10)'; y = [sin (x) cos (x)]; line (x,y)Create x and y as vectors. Then call the low-level version of the line function by specifying the data as name-value pair arguments. When you call the function this way, the resulting line is black. x = linspace (0,10); y = sin (x); line ( 'XData' ,x, 'YData' ,y)

If you set the line width to a value that is less than the width of a pixel on your system, the line displays as one pixel wide.
