I want to find frequency of occurrence histogram of paired values in 3d. I have two variables and values taken with same time. A=[1.1;2.3;2.5;1.1;1.6;1.1;2.3] and B=[3.3;2.1;1.2;3.3;2.1;3.3;2.1]. these values taken at 7 different time intervals.

Try histogram2():
A=[1.1;2.3;2.5;1.1;1.6;1.1;2.3]
B=[3.3;2.1;1.2;3.3;2.1;3.3;2.1]
numBins = 5;
histogram2(A, B, numBins)
xlabel('A', 'FontSize', 20);
ylabel('B', 'FontSize', 20);

It was introduced in R2015b. Can you upgrade? You're now 2 years behind.
Otherwise look at hist3() or similar functions.
