how to calculate the maximum consecutive dry days and wet days over time period?

I have matrix (189x189) of daily precipitation in 20 years period (7300 files). I want to calculate the consecutive dry days and wet days in that period, where dry days is RR<1 and wet days is RR>1. can any one help me about this problem?

Is 189X189 matrix is RR?

[Tomi Afrizal]

yes, 189x189 is matrix of RR.

RR=randi([-255,255],189,189); % Prepare a random precipitation data %Assumption that RR is matrices of 189x189 and containing precipitation data if this assumption is correct then below mentioned steps will work dryDays=RR<1; noOfDryDays=find(dryDays); noOfWetDays=find(~dryDays);

Or Else First you need to import data in a variable then use above code snippets

[Tomi Afrizal]

what is mean of [-255,255]? in this case I want to calculate the maximum number of consecutive dry days and wet days over 20 years period, that mean how many days in this period have consecutive dry days and wet days. I hope you can help me about this.

The above attached codes are not working

error in this line[StartDay,Enddate,maxdryconsDay]=ConsecutiveCalcDays(noOfDryDays). Kindly solve
