WebOct 10, 2015 · x (1) = 0 and y (1) = 0 is very similar to initializing a list / array in Python where x and y are the list variables and the first position is 1. MATLAB starts indexing at 1, and not 0 like in Java and Python. The similar syntax in Java or Python is: x [0] = 0; y [0] = 0. MATLAB uses round braces to index into an array / vector / list. http://www.ece.northwestern.edu/local-apps/matlabhelp/techdoc/ref/uint8.html
