I want to compare enteries of 2 arrays and if they follow the condition, store the value at the same index in a separate array.
The following code is giving me an error. Please let me know what else can I use?
I want to return the 2D array M_filter_1
M =[1 2 3 ; 8 9 0];
e = 2;
M_filter_1=[[]];
n = size(M,2)
m = size(M,1)
A =[1 2 3 4 5 6 7 8 9 0];
for k = 1:1:size(A,2)
for i= 1:1:m
for j = 1:1:n
if (M(i,j)> A(k) - e) & (M (i,j)< A(k)+ e)
M_filter_1(i,j) = M(i,j);
else
M_filter_1(i,j)= 0 ;
end
end
end
end

M =[1 2 3 ; 8 9 0];
e = 2;
m = size(M,1);
n = size(M,2);
M_filter_1 = zeros(size(M));
A =[1 2 3 4 5 6 7 8 9 0];
for a = A
for i= 1:1:m
for j = 1:1:n
if (M(i,j)> a - e) && (M (i,j)< a + e)
M_filter_1(i,j) = M(i,j);
end
end
end
end
