Sum through an array until a value is reached, then continue

7 次查看(过去 30 天)
Assume you have 2 arrays x = linspace(0.001,0.005,1000); y = linspace(0,1,1000);
I want to start at the beginning of x, and sum consecutive columns until the sum = 0.1, then take the average of y across that range.... then continue doing this until the end of x

"With the values given, the first 100 columns would sum to 0.1"
No body know where the 100 comes from. Anyone is guessing and people just wastes theirs times for you.
Not give example is better than give one that doesn't make sense.

c=cumsum(x);
G=discretize(c, 0:0.1:c(end));
result = splitapply(@mean, y, G),

sumx = cumsum(x);
meanybelowthreshold = mean(y(sumx <= 0.1));
meanyabovethreshold = mean(y(sumx > 0.1));
