how to find the days haven't been precipitations in a vector or a file.

Need to solve this, every help would be nice, thanks.

Specially the most difficul one is to find the days when have been no precipitations.

Implement a function called computePrecipitationStats which, given the vector that contains the daily precipitations and a threshold value, returns the average daily precipitation, the standard deviation of the daily precipitations, the number of days with no precipitation and vector containing the days when the precipitation was above the specified threshold.

I need to know how to calculate how many elements there are with value 0 in the vector. I have written the exercise to put people in context of the problem.

sum(x == 0)
% or:
numel(x) - nnz(x)

Hints:

v = randi([0, 5], 1, 20)

v = 1×20

5 2 3 1 5 1 4 4 3 0 5 3 5 2 2 5 0 2 3 4

numZeros = sum(v == 0)

numZeros = 2

valuesAboveThreshold = v(v > 3) % 3 is the threshold

valuesAboveThreshold = 1×8

5 5 4 4 5 5 5 4
