How to choose values from vector (150 000x1). When i need first 512 values for x, next 512 values for y and next 512 values for z. And separate vector by this style to the end

Hello everyone,

I have vector aproximatly (150 000 x 1) and i need to separate values to separate vectors (x,y,z). First 512 values of global vector is for X, next 512 values is for Y and next 512 values is for Z. And this repeats to the end of the vector. Does anyone know, how to sort values please?

Thank you so much.

XYZ=reshape(V,512,[]);

then process by column. Most MATLAB functions operate by column natively; depending upon what you're doing with the data, you may be able to do it all with vector operations.

NB: the "approximately 150000" elements will have to be exactly a multiple of 512 for the above to work without some bookkeeping to select the proper number overall or to augment to the next multiple.
