suppose, data = [15 2 7 16 16]; and there are 16 different files in the workspace how to call it according to the 'data' vector in bunch of five(as sequence shown in data vector)

"and there are 16 different files in the workspace"
Please expand on that. Files can be on disk, but only variables can be in a workspace.

MS = {M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16};
MS(data)
The result will be a 1 x 5 cell array that you would typically use {} indexing to access the contents of.
This code does not assume that the M variables are the same size or are the same data type.
In the case that the M variables are the same size and are a numeric data type, then there are other possibilities, such as
nd = ndims(M1);
MS = cat(nd+1, M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11, M12, M13, M14, M15, M16);
idx = [repmat({':'}, 1, nd), {data}];
MS(idx{:})
This would in this special case give you a numeric array that is one dimension higher than your original arrays, with the extra dimension corresponding to the entries in data. For example if your M variables are all 1024 x 768 x 3 RGB images, then MS would be 1024 x 768 x 3 x 16 and the indexed version would be 1024 x 768 x 3 x 5
