I have a cell of size 24x1. It is of the form k1 =
[ 13]
[ 13]
[ 13]
[ 13]
[ 13]
[ 13]
[ 0]
[ 12]
[ 12]
[0x1 double]
[ 12]
[ 12]
[ 12]
[ 11]
[ 11]
[ 11]
[ 11]
[ 11]
[ 11]
[ 9]
[0x1 double]
[ 10]
[ 10]
[ 10]
I want to detect the Empty Matrix: 0-by-1 cells in k1. For example, at k1(10), the value is [0x1 double]. I want to convert k1 into matrix and replace these empty matrices([0x1 double]) with zero. How can i do this?

bla = {1:3,[],4}
your_logical_result = cellfun(@(x) isempty(x),bla)
bla(your_logical_result) = {0}

Thanks, good to know. Not very intuitive if you ask me.
