MATLAB: Determining length of values in cell

Question

Hi,

I have a single column cell with numbers between 1 – 5 (each allocated to a behaviour). This is used to plot a line graph so I can see what behaviour occured at each given time period. My question: Is there a way to extract features such as for Step it occurs when the behaviour "4" is represented on the line graph for greater than 700 data points. Is there a way I can do that?

And also determine how many times in the cell the behaviour changes. Not sure if this makes sense. Ask me to clarify otherwise.

Thanks

Katrina

If A is your data...you can use logicals like ==, >, < etc..to find the locations. For example, if you want where 4 is present. If the data is in cell, you need to use flower braces: A{1} ....

idx = find(A==4) ;
