  1. I0 = false(1000); % create logical matrix.
  2. ind = randperm(1000^2,7); % random position to place.
  3. I0(ind) = 1; % place ‘one’
  4. I1 = imdilate(I0,circlePixels); % place circles.
  5. imshow(I1)

How do you graph a sphere in Matlab?

To draw the sphere using the returned coordinates, use the surf or mesh functions. [X,Y,Z] = sphere( n ) returns the x-, y-, and z- coordinates of a sphere with a radius equal to 1 and n -by- n faces. The function returns the x-, y-, and z- coordinates as three (n+1) -by- (n+1) matrices.

How do you draw a circle in octave?

In Matlab you can draw a circle by just specifying the center and the radius like this: R = 10; Center = [5,8]; circle(Center,R,1000,’b-‘); hold on plot(Center(1),Center(2),’g. ‘)

How to plot a circle in MATLAB SlideShare?

Step: calculate the vertical values of your points: y = sin (angle); 4. 4th. Step: plot your 360 pairs of x and y values: plot (x, y) 5th. Step: force your x distance to equal your y-distance in the plot: axis (‘equal’) 5.

How to create a circle using rectangle function in MATLAB?

Let us now learn how to create a circle in MATLAB using rectangle function: Here is a simple code to achieve this: 1 Like we discussed in above examples, we will declare the radius and centre co-ordinates of the required circle. 2 We have passed ‘FaceColor’ as “b” so our output circle will be of Blue colour.
