I want to exchange data from a Workspace struct with my own data. Sounds easy but: MY data (lets call it y) y is a 700x1 double. The data x from the struct is 9000 times 700x1 double. So how can i tell matlab to get in to the struct and exchange every 9000 x with my y. I hope you did understand my question.
I attached an image so you can see i want to do.

This is one of the rare case where deal is useful:
[] = deal(y);
Note that your structure is called data and so is the field of the structure. Please come up with some more meaningful names.
I have to ask, what is the point of storing 9599 times the same data?

ahh yes. if you´re still interested in why i stroe 9000 times the same data. i wanted to make an own ideal spectra of gaussiancurves. Cuz of second order correlation you need like 10000 spectra to calculate pulse duration out of it. Now i have another question for you. I am still working with deal. but thats the bottleneck of my code. its slows me down really hard. I have to copy a matrix of 700x9000 data points into a struct, as seen in the picture. Do you have any ideas how to speed that up?
