How to create many variables from a dataset?
Afficher commentaires plus anciens
I have a dataset having 369148 rows organised in two columns. Every 26 rows of the first column contains a specified scale and the next 26 rows a different scale and so on. Second column contains measurement values at every specified scale. Therefore, total 14198 scales each having 26 measurement values making a grand total of measurement values in the second column is 369148. I want to create 14198 variables for every specified scales each having 26 measurement values. Can someone help me out.

Reshape the original data set so that each of your "variables" is stored as a column of the data.

Enjoy reading! Basically you should keep your data together as much as possible, because this makes MATLAB fast, and is neater to code. Learn to use the dimensions of numeric arrays rather than splitting up your data:

You can reshape your data
data = reshape(data, 26, 14198, 2);
You can even let Matlab figure out the elements along the 2nd dimension
data = reshape(data, 26, [], 2);
