How can I make automatic calculation for averages for given ranges?

I have 4 case with different x and y values. I want to combine these 4 cases. When doing this combination, if there are some x values in common then I want to take average. Basically, there are 4 case and I want to combine them according to their inputs ( x ). First A, x is between 0.0703-0.1771 Second B, x is between 0.0937-0.2361 Third C, x is between 0.1406-0.3541 Fourth D, x is between 0.2812-0.7083.
I want to calculate y values in average. If there are some x values in use for 2 or 3 case (i.e. 0.1505 is in A, B and C) to take average I want to divide by number of case that include this value. For example, x from 0.0703 to 0.0936, there is only one case, then no need to take average.
Thank you in advance.

Not sure I follow. Hopefully you have arrays and not a bunch of separately named variables, like y24 is really y(2,4). Anyway, check out ismembertol() and see if it does what you want.

Try this:
range1 = x >= 0.0703 & x <= 0.1771
range2 = x >=0.0937 & x <=0.2361
range3 = x >= 0.1406 & x <=0.3541
range4 = x >= 0.2812 & x <=0.7083
sumA = sum(A(range1));
sumB = sum(B(range2));
sumC = sum(C(range3));
sumD = sum(D(range4));
numTerms = sum(range1+range2+range3+range4)
overallMean = (sumA + sumB + sumC + sumD) / numTerms
