How to split a large variable.

Hi,

I have a variable called P_rs which contains 96000x9801 (double). I'd like to divide it into smaller variables in multiples of 99 columns (below) and include all of these in a structure for easier save. Is there an easier way of doing this? (i.e. for loop etc.)

P_rs_01 = P_rs(:,1:99); P_rs_02 = P_rs(:,100:198); P_rs_03 = P_rs(:,199:297); P_rs_04 = P_rs(:,298:396); P_rs_05 = P_rs(:,397:495); P_rs_06 = P_rs(:,496:594); P_rs_07 = P_rs(:,595:693); P_rs_08 = P_rs(:,694:792); P_rs_09 = P_rs(:,793:891); P_rs_10 = P_rs(:,892:990); P_rs_11 = P_rs(:,991:1089); P_rs_12 = P_rs(:,1090:1188); P_rs_13 = P_rs(:,1189:1287); P_rs_14 = P_rs(:,1288:1386); P_rs_15 = P_rs(:,1387:1485); P_rs_16 = P_rs(:,1486:1584); P_rs_17 = P_rs(:,1585:1683); P_rs_18 = P_rs(:,1684:1782); P_rs_19 = P_rs(:,1783:1881); P_rs_20 = P_rs(:,1882:1980); P_rs_21 = P_rs(:,1981:2079); P_rs_22 = P_rs(:,2080:2178); P_rs_23 = P_rs(:,2179:2277); P_rs_24 = P_rs(:,2278:2376); P_rs_25 = P_rs(:,2377:2475); P_rs_26 = P_rs(:,2476:2574); P_rs_27 = P_rs(:,2575:2673); P_rs_28 = P_rs(:,2674:2772); P_rs_29 = P_rs(:,2773:2871); P_rs_30 = P_rs(:,2872:2970); P_rs_31 = P_rs(:,2971:3069); P_rs_32 = P_rs(:,3070:3168); P_rs_33 = P_rs(:,3169:3267); P_rs_34 = P_rs(:,3268:3366); P_rs_35 = P_rs(:,3367:3465); P_rs_36 = P_rs(:,3466:3564); P_rs_37 = P_rs(:,3565:3663); P_rs_38 = P_rs(:,3664:3762); P_rs_39 = P_rs(:,3763:3861); P_rs_40 = P_rs(:,3862:3960); P_rs_41 = P_rs(:,3961:4059); P_rs_42 = P_rs(:,4060:4158); P_rs_43 = P_rs(:,4159:4257); P_rs_44 = P_rs(:,4258:4356); P_rs_45 = P_rs(:,4357:4455); P_rs_46 = P_rs(:,4456:4554); P_rs_47 = P_rs(:,4555:4653); P_rs_48 = P_rs(:,4654:4752); P_rs_49 = P_rs(:,4753:4851); P_rs_50 = P_rs(:,4852:4950); P_rs_51 = P_rs(:,4951:5049); P_rs_52 = P_rs(:,5050:5148); P_rs_53 = P_rs(:,5149:5247); P_rs_54 = P_rs(:,5248:5346); P_rs_55 = P_rs(:,5347:5445); P_rs_56 = P_rs(:,5446:5544); P_rs_57 = P_rs(:,5545:5643); P_rs_58 = P_rs(:,5644:5742); P_rs_59 = P_rs(:,5743:5841); P_rs_60 = P_rs(:,5842:5940); P_rs_61 = P_rs(:,5941:6039); P_rs_62 = P_rs(:,6040:6138); P_rs_63 = P_rs(:,6139:6237); P_rs_64 = P_rs(:,6238:6336); P_rs_65 = P_rs(:,6337:6435); P_rs_66 = P_rs(:,6436:6534); P_rs_67 = P_rs(:,6535:6633); P_rs_68 = P_rs(:,6634:6732); P_rs_69 = P_rs(:,6733:6831); P_rs_70 = P_rs(:,6832:6930); P_rs_71 = P_rs(:,6931:7029); P_rs_72 = P_rs(:,7030:7128); P_rs_73 = P_rs(:,7129:7227); P_rs_74 = P_rs(:,7228:7326); P_rs_75 = P_rs(:,7327:7425); P_rs_76 = P_rs(:,7426:7524); P_rs_77 = P_rs(:,7525:7623); P_rs_78 = P_rs(:,7624:7722); P_rs_79 = P_rs(:,7723:7821); P_rs_80 = P_rs(:,7822:7920); P_rs_81 = P_rs(:,7921:8019); P_rs_82 = P_rs(:,8020:8118); P_rs_83 = P_rs(:,8119:8217); P_rs_84 = P_rs(:,8218:8316); P_rs_85 = P_rs(:,8317:8415); P_rs_86 = P_rs(:,8416:8514); P_rs_87 = P_rs(:,8515:8613); P_rs_88 = P_rs(:,8614:8712); P_rs_89 = P_rs(:,8713:8811); P_rs_90 = P_rs(:,8812:8910); P_rs_91 = P_rs(:,8911:9009); P_rs_92 = P_rs(:,9010:9108); P_rs_93 = P_rs(:,9109:9207); P_rs_94 = P_rs(:,9208:9306); P_rs_95 = P_rs(:,9307:9405); P_rs_96 = P_rs(:,9406:9504); P_rs_97 = P_rs(:,9505:9603); P_rs_98 = P_rs(:,9604:9702); P_rs_99 = P_rs(:,9702:9801);

Read about reshape. You can split your data into 3D matrices and use it later.

A = rand(96000,9801) ;
B = reshape(A,9600,99,[]) ;
