let
A=[1 0 0 0 0 0 0 1; 1 1 1 1 1 1 0 1; 0 0 0 0 0 0 1 1; 1 1 1 1 1 1 0 1; 0 0 0 0 0 0 1 1]
how to cluster this matrix A?

Under at least two reasonable definitions of "cluster", all of the values that are 1 are in one cluster and all of the values that are 0 are in another cluster. The most obvious "reasonable definition" there involves value, but it also happens that if you use 8-connectivity then every 1 value is "connected" to every other 1 value through a chain.
My speculation is that what you want is bwlabel() with 4 connectivity.

That's my guess too.
[labeledImage, numberOfRegions] = bwlabel(A);

sir i want same pattern bit strings in one cluster for example: bit strings [1 1 1 1 1 1; 1 1 1 1 1 1] in one cluster suppose this is cluster 1, now bit strings[ 0 0 0 0 1 0; 0 0 0 0 1 0] are in another cluster let cluster 2...and so on..it means same pattern bit strings should be in one cluster..which cluster algorithm is best suited for this type of clustering ..

[clusters, ~, clusteridx] = unique(A,'rows');

thank u..sir can i do clustering of binary matrix using hamming distance..?actually i m working on spatio-temporal data[maternal health data] so i have a binary matrix of fixed length and In the matrix 0 represent increase and 1 represent decrease..now i want to cluster the binary strings of same pattern in one cluster i mean those bit strings which shows the same behaviour should be in one cluster..how can this be possible using hamming distance..if u have any idea please help me..
