For equal intervals, separated by delta:
discrete_x = floor( (x - minimum_allowed_x) ./ delta ) .* delta + minimum_allowed_x;
For unequal intervals in which the left edges are given by the vector edges and the last entry of edges is the upper bound:
[~, ~, bin] = histcounts( x, edges );
discrete_x = edges(bin);

[~, discrete_x] = histc(x, edges);
discrete_x(discrete_x == length(edges)) = length(edges)-1;
discrete_x(discrete_x == 0) = NaN;
