how can i create this image in matlab

[John D'Errico]

Trivial. You already have the image. So read it into MATLAB, using imread.

i want to create this image using different functions in matlab

[Star Strider]

Use the patch and annotation functions.

Is that supposed to be one object, or nine adjacent objects with different color/hatch fills?

Are the dimensioning marks required in the output?

What is the intended output? Do you want a ephemeral graph in a figure, or a raster image array that can be saved? Or are you trying to actually create some sort of vector image or STL file?

EDIT:

Also, how exactly is the length of the object defined?

• Is it defined as certain number of edge cycles N of length period, such that the object is N*period long?
• Is the object length + period/2 long -- in which case there are 1+(length - period/2)/period edge cycles? Is there any assurance that (length - period/2) is integer-divisible by period?
• Is there a certain number of edge cycles N-1/2 within length -- in which case period is length/(N - 1/2)?

What are the actual parameters that unambigiously and completely describe the object geometry?

this is a single image.

Without clarification, I'm going to take the liberty to assume that you want a plain line plot with no dimensioning marks.

% parameters
l = 100;
w = 50;
x = 10;
y = 10;
n = 4;

% build one cycle
xx = [0 x x l/n];
yy = [0 0 y y];

% expand to n cycles on one side
xx = reshape(xx(:) + (0:n-1)*l/n,1,[]);
yy = repmat(yy,1,n);

% flip to create other side
xx = [xx flip(xx)];
yy = [yy w-flip(yy)];

% close the path
xx = xx([1:end 1]);
yy = yy([1:end 1]);

plot(xx,yy)
axis equal

how can i convert this into a function. and when i call the function i want to get the image
