How do I find and assign the x and y values of a point from an index array based on the value of z?

Hello,
I am using an extracted column for finding a specific point.
V=F1(:,1); %F1 is the data of a matrix
When I display the data, the x, y, and z values are shown on a figure on coordinate I. Lets say if I want to have V (the first column in the matrix) scanned from top to bottom (or vice versa) for one specific point in the column to find a z value where if z>100, the one point will assign a value for x (x1) and y (y1).
What approach might come handy to find and assign the x and y value (recorded as x1 and y1) if I have an extracted column if Z>100.

Perhaps:
index = find(F1(:,1) > 100, 1, 'last'); % or 'first'
x1 = x(index);
y1 = y(index);
But this is pure guessing only. Better improve the question.
