Hi
My data are in a single column but:
First two rows - are just labels
3rd row contains two numbers->something like time base (0.001 and 0.000001 for example)
4th row as above but here -> matrix dimension (usually 24 x 40 - but first (24) number vary from one dataset to another)
next row can be skipped - not important
row 6 to 29 (but depends on first number from 4th row-here 24) -> let's call it tau values, should be multiplicated by 0.001 from 3rd row
row 30 to 69 -> t values*(0.000001 from 3rd row)
Now think about t and tau as XY plane
row 70 to 109 -> "Z" values "along" t axis for first tau value
next rows - as above but for remaining 23 values of tau
my QUESTIONS are:
-is it possible to built such a matrix
-if so - is it possible to make calculations on a given row or column
Many thanks in advance!! |

Hi
Thank you for the response
But it is not so simple -
If I prepare the data in the way you mentioned I'll have:
X-col with 24 rows (=a-because this number changes from one measurement to another, of course constant for a given dataset)
Y col with 40 rows (always)
Z col with 40*a rows
Moreover, none of these valus are equally spaced...
So, which method of conversion shoud I use??

Hi:
To convert your data into a matrix, you should remove the redundancy rows and place your tau, t, z value into three columns, XYZ, respectively.
