How to copy and add a matrix for a large number of times?
in [Matlab]

From: Wei He on 30 Jun 2010 05:26 Hello, everyone. I generated a matrix 125*16 (matrix1). And then, I want to copy it for 50 time and connected to the end of the first matrix for 80 times in order to produce a 10000*16 (Matrix). To add it like this : Matrix = [matrix1;matrix;matrix;.....] is troublesome very much. Is there any convenient way to do it? Thanks in advance~!! Wei.

I currently generate it like this: matrix = [matrix1;matrix1;matrix1;matrix1;matrix1;matrix1;matrix1;matrix1;matrix1;matrix1]; matrix = [matrix;matrix ;matrix ;matrix ;matrix ;matrix ;matrix ;matrix ]; it still seems not convenient. Is there any fucntion that could define the a specific number of the times?

Is there any fucntion that could define the a specific number of the times? did you take the time to read what was told you above(?)... or are you simply repeating your OP without reflection... us
