Problem binning data with histc()

8 views (last 30 days)
John on 23 Jan 2013
I am trying to bin velocity and acceleration data using histc(). However, I am getting an error. I would be grateful if somebody could advise me on how to do it correctly?
I have velocity and acceleration in 2 columns. For example
Vel Acc
1 0.28
2 0.28
2 0.00
3 0.28
5 0.56
6 0.28
I am trying to bin the data into the bins, specified by the bin edges.
edges = {0:1:120, -4:0.1:4}
I was trying to use the histc(). Using the code:
But I am getting the error:
Edge vector must be monotonically non-decreasing.
Could you tell me the correct way of defining the edges of the bins. I also tried a vector but that wouldn't work.
Ultimately, I trying to create a plot like this.
Thank you

N = hist3(Data, 'Edges', edges);
N would then be counts and nothing would be plotted.

Why do you think you can use the syntax
that is not a supported syntax.
edges must be a vector or matrix. It is not a name-value pair as you have entered.
To do it correctly, something like
Data = randn(1000,1);
Edges = -3:0.5:3;
N = histc(Data,Edges);
