Finding maximum overlaps in a matrix

Hi All,

I have an input matrix as shown. How do I calculate for which values the maximum overlap occurs? i.e, as you can see the maximum overlap is somewhere between 0.5 and 3e-5. How do I do this using MATLAB? I tried using regression function but it does not seem to work.

The x-axes represent current values and the y-axes represent the voltages. I need to to be able to say that in this case, for example, we have say an overlap of 11 or 12 inputs (y-values). So this is for what x-range?

Please assist. Thanks! This second figure below shows basically the points for which the x-axes values I need to find as they all lie along the same y- axes.

Do you have the x and y values stored, or only this image?

Assuming you have the x and y values, do you want the single x value with the most overlap, or if you want a range, how is the range constrained (how big can it be)?

Thanks John...the latter part exactly...the range...there is no constraint in the range..it should be with the maximum overlaps...In this case we have like 16 inputs...so it could be between say, 11-16..

An example matrix rather than a graph we can't test any code with would be extremely useful.

Are the x values discretised? If not, is it acceptable to discretise them in fixed bins and count the population of each bin?

Yes..its a 16x16 matrix. As an example,

nn =randn(16,16);
figure();plot(nn,'*b');

use max function

Could you explain with an example?
