I have this variable:
>> out1
ans =
Columns 1 through 5
[899x5 double] [899x5 double] [899x5 double] [899x5 double] [899x5 double]
Columns 6 through 10
[899x5 double] [899x5 double] [899x5 double] [899x6 double] [899x6 double]
Columns 11 through 15
[899x6 double] [899x6 double] [899x6 double] [899x6 double] [899x6 double]
Column 16
[899x6 double]
And I want to substract at each columns of the out variable the third element of each [899*5] or [899*6]

I want to substract at each columns of the out1 variable the third element. A sort of this line of code:
bsxfun(@minus, prova,prova(3,:))

This code read the first element of the third rows of the out1 variable and substract each for all the columns?

For each matrix out1{i}, it subtracts the 3rd row from all of the other rows.
