Read STL FILE on MATLAB

Hello, I am doing my school project and have encountered this problem of reading STL file on MATLAB. The STL file has 7706 KB, i am trying to reduce the patch/mesh but I couldn't move on without reading the STL file on matlab first. Please help me out. Thank you very much.

No, this is not how a function is called in MATLAB. Read here: https://www.mathworks.com/help/matlab/matlab_prog/create-functions-in-files.html. You cannot pass input when declaring the function. Which means that first line should be like this

function [coordinates] = stlread(filename)
..
..
fid = fopen(filename);
end

After declaring the function, you can call it like this

stlread('test.stl')

So your file should be like this

clear; % don't use clear all
clc;

coordinates = stlread('test.stl')

function [coordinates] = stlread(filename)
..
..
fid = fopen(filename);
end

and then run the script.

Note that from R2018b, MATLAB also have its own stlread() function. You can also use that.
