defining matrix for a loop

hi

i need to define a matrix to write an output.

the code i used is

txtFiles = dir('*.txt') ;
N = length(txtFiles) ;
PSDsheet = zeros( N,16);
..........................
........................
.........................
 PSDsheet (n,:) = AllPSD

while im running this 'Unable to perform assignment because the size of the left side is 1-by-16 and the size of the right side is 3-by-16'.

Please help me what i need to modify.

txtFiles = dir('*.txt') ;
N = length(txtFiles) ;
PSDsheet = cell( N,1);
..........................
........................
.........................
 PSDsheet{n} = AllPSD

OR

txtFiles = dir('*.txt') ;
N = length(txtFiles) ;
PSDsheet = zeros( N,3,16);
..........................
........................
.........................
 PSDsheet(n,:,:) = AllPSD

Bottom line either save them into cell if you don't know dimensions or save them into 3D matrix if you know the dimensions.

You are getting error becuase, you are trying to save more number of elements than initalized for.
