MATLAB: How to search about a matrix in a cell

cellcell array

Hello,

Suppose that I have the cell matrix A which contains the following elements:

A={ 
[0;0] [0;1] 
[1;0] [0;0]
}

So I want to use a line of code that can count how many [0;0] are in each row ?

Regards,

it's always a good idea to give the result you expect for your example to avoid ambiguity.

A={ 
[0;0] [0;1] 
[1;0] [0;0]
}
sum(cellfun(@(x) isequal(x, [0;0]), A), 2)

results in

ans =
     1
     1

count of [0;0] in each row.

You were close when using diff. You need to think what characterizes all four combinations. The code below should be what you need.

v=[1;1;0;0;0;1;0;1;0;1];
d=diff(v);
u=v(1:(end-1));%shrink by 1 to make it the same size as d
clc
%if [0;0]
%then diff==0, v==0
L= d==0 & u==0;
fprintf('[0 0]: %d\n',sum(L))
%if [0;1]
%then diff==-1
L= d==-1;
fprintf('[0 1]: %d\n',sum(L))
%if [1;0]
%then diff==1
L= d==1;
fprintf('[1 0]: %d\n',sum(L))
%if [1;1]
%then diff==0, v==1
L= d==0 & u==1;
fprintf('[1 1]: %d\n',sum(L))
