How can I break a long column vector (281820X1) into 140 short column vectors (2013X1)?

1 回表示 (過去 30 日間)
I collected the raw data from a Raman image which acquired 140 Raman spectra from a 14X10 rectangular area. The resulting data file contains 281820 rows for all the spectra so how should I restore the 140 individual data files?

data = (1:281820)';
cols = 140;
rows = numel(data) / cols;
data_reshaped = reshape(data, [rows cols]);
Name Size Bytes Class Attributes cmdout 1x33 66 char cols 1x1 8 double data 281820x1 2254560 double data_reshaped 2013x140 2254560 double rows 1x1 8 double
Also, if you are just getting started with Matlab, I would highly recommend that you take a couple of hours to go through the free online tutorial: Matlab Onramp
