Reading a line of binary file MATLAB

I am new in using MATLAB and I want to do a simple thing: I want to read a binary file that contains rows like this

32156432

345243867

454154351

35477

5641871

....

I know that the fread() in MATLAB reads the file byte by byte, but I want to read the value that there is on each line. All values are uint32_t and the file is generated with a script in C++ with just a printf, the values are printed in a file like my_file.bin launching the executable in this way ./executable param1 >> my_file.bin

You can use the function fscanf

Sample Code:

fileID = fopen('my_file.bin','w');
x = 32156432;
y = 345243867;
w = 454154351;
fprintf(fileID, '%d\n',x);
fprintf(fileID, '%d\n',y);
fprintf(fileID, '%d\n',w);
fclose(fileID);

fileID = fopen('my_file.bin','r');
formatSpec = '%d';
A = fscanf(fileID, formatSpec);
