I have an array of length x (lets say 10) and I want to split the array at every occurence of the value 0.

For example A = [0,3,5,6,9,0,2], I want to form two separate array from this being B=[3,5,6,9] and C=[2]

Taking into consideration that the 0 could be anywhere in the array, could be in any number of occurences and could even not exist at all.

在 MATLAB Online 中打开

A = [0,3,5,6,9,0,2]
A = 1×7
     0     3     5     6     9     0     2
mask = A == 0;
starts = strfind([true mask], [1 0]);
stops = strfind([mask true], [0 1]);
output = arrayfun(@(T,P) A(T:P), starts, stops, 'uniform', 0);
celldisp(output)
 
output{1} =
 
     3     5     6     9

 
 
output{2} =
 
     2
