If you want to assign emptys array to the contents of those two cells, you can use the brackets ([]) and deal:

[a{[6 23]}]=deal([])

If instead you want to remove those two cells entirely, use parentheses:

a([6 23])=[]

The reason a{[6 23]}=[] gives an error is because accessing a cell array that way returns a comma-separated list of the cell contents. In other words, doing [a{[6 23]}] is like doing [a{6},a{23}].
