How to generate a square lattice structure.

In the attached image there is a square lattice shaped structure of air holes. Please tell me how to generate it using matlab code.

it is interesting!

It can be done on Abaqus also!

Hi Subhashish,

I am not sure about your use case for developing this square lattice structure. Do you want it for some kind of analysis?. In case you just want the MATLAB code to draw this figure, You can use the ' rectangle ' function to draw out the main square frame and then use the ' viscircle ' function to draw the circles. Note that the 'viscircle' function is a part of the Image processing Toolbox. If you don't have one, you can use the 'rectangle' function to draw the circle as well by setting the curvature property to [1 1]. You can also refer to the ' Pattern Generator for MATLAB ' File Exchange submission that seems to generate similar lattice structures.

Hey Rohit, are you proficient enough in matlab. I have a code with me and want to modify it for generating square lattice. it currently generates hexagonal lattice.

[AQSA]

hi Subhashish can you please send me the code for hexagonal lattice

[Mariam Kavai]

Hi subhashish, could you please send me the code for a hexagonal lattice. I appreciate it.

1st

create zeros materix

2nd

create disc materix

3rd

set for function to add the disc into the zeros materix

from here you can set the diatnce btween each disc

4th

gaussan the final image to obtain similar image as you can see in any TEM image
