Reading existing function in MATLAB?

I have download some function of Matlab for my project work. Now when I am running that function then it is showing error

Error: >> stlRead

Execution of script stlRead as a function is not supported:

I:\Python coding\3d\New findings\vsangelidakis\vsangelidakis-SHAPE-f97791a\lib\stlTools\stlRead.m

Error in stlRead (line 1)

[v, f, n, name] = stlRead('aggregate_1.stl');

I am attcahing the folder of the function.

The issue is that your function name is strReads, not stlRead. However, it is best practice to use the same name for the function and the file. You function is actually called stlGetFormat. You should rename your file so that it has the same name as your function, and use that name to call it.

type stlReads.m

function format = stlGetFormat(fileName)
%STLGETFORMAT identifies the format of the STL file and returns 'binary' or
%'ascii'

fid = fopen(fileName);
% Check the file size first, since binary files MUST have a size of 84+(50*n)
fseek(fid,0,1);         % Go to the end of the file
fidSIZE = ftell(fid);   % Check the size of the file
if rem(fidSIZE-84,50) > 0
    format = 'ascii';

Incidentally, MATLAB has an stlread function.

unzip('aggregate_1.zip')
TR = stlread('aggregate_1.stl')

TR = 
  triangulation with properties:

              Points: [13535x3 double]
    ConnectivityList: [27066x3 double]

trimesh(TR)
