From: subbu on 12 May 2010 22:33 I have a single row matrix with 121 columns. I want to make a new matrix with first 10 elements as 1st row, second 10 elements as 2nd row,.......12 rows and last row has a single element. is there a command to do this? because i need to repeat this step for a big matrix of dimension 21 x 121. please help me. thank you in advance cheers

You cannot have a matrix with 10 elements in some rows and a single element in the final row.

But i need this matrix as an input to other code that im running, and that code accepts the file only if it is in "10f10.3" format. Thats why i need to decompose this matrix. doing it manually 121 times is a bit cumbersome. It will be good to know if there is any command that can do this job. cheers thanks in advance
