Substract element of a matrix!

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,:))

Answer 1

[Matt J]

 cellfun(@(c) bsxfun(@minus, c,c(3,:))  , out1,'uni',0)

[Francesco]

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

[Matt J]

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