You must know the format of binary file to read. Do you know the format? Doc fread

There is an infinite number of binary formats. The file extension "bin1" does not reveal, how the data are stored internally. It could be a vector of double values, or perhaps it starts with the dimensions as UINT64 vector and then the values are stored as single. This cannot be predicted and an examination of the data is not reliable also. You have to ask the person, who has written the file, or read the corresponding docs.
If you know the structure of the file, fread allowes to read the parts. Finally csvwrite creates the wanted file.

fid = fopen('test2.bin1');
data = fread(fid, '*uint8');
data = reshape(data, 32, []);
imshow(data);
Or possibly
data = reshape(data, 1, []);
imshow(data);

fid = fopen('test2.bin1');
temp = fread(fid, [2 inf], 'uint16=>double');
fclose(fid);
data = complex(temp(1,:), temp(2,:));
Note: all of the complex components are 0.
You appear to have pulses of width 63 or (more often) 64, that are placed 125 or 126 apart. So this is basically a square wave with a duty cycle just slightly greater than 1/2
