hi, I want to split my data set into different series lets say its from 2.0 to 2.99 I want to make intervals like 2.00 - 2.199, 2.2-2299, 2.3-2.3999 and then would like to to count the number of values for each interval.

hi, I want to split my data set into different series lets say its from 2.0 to 2.99 I want to make intervals like 2.00 - 2.199, 2.2-2299, 2.3-2.3999 and then would like to to count the number of values for each interval.

Next would be to write a loop to measure the value Cumulative Total Above Lower value in Ranges

Please help

It is called a histogram count. There are several MATLAB functions that can do the counting with your data and your bin ranges as input. The histc function is closest to what you want to do.

I have no idea what you mean by ‘measure the value Cumulative Total Above Lower value in Ranges’, so please describe what you want to do in a bit more detail.

在 MATLAB Online 中打开

Try this:

values = [...
745   
422  
876  
477   
440  
674
600 
450 
630 
439  
432  
483]
edges = 2 : 0.1 : 3
counts = histc(values, edges)
cdf = cumsum(counts)'
backwardsCDF = fliplr(cdf)
