Finding a maximum y value for each x values
显示 更早的评论
I have an the x axis (from -3.1 to -2.4 separated by .1) and a y axis that has several points on each value for x. The y values range from -20 to 100.
I am trying to find the minimum and maximum y value for each value of x.
How would I approach this? I am assuming I need the min and max functions, but it only gives me one single point.

It really depends on how the data is arranged (i.e. how the arrays are shaped, whether they're sorted, etc). For a concrete example, you should probably give a more concrete description of what you're working with.

G=findgroups(x);
Maximums=splitapply(@max,y,G);
Minimums=splitapply(@min,y,G);
