unix - Reading zipped sas datasets and zipping them on the fly -


i working large files on unix server gzip compression capabilities , space purposes files remain zipped. know how read in zipped txtfile, to: 1) zip dataset created zipped txtfile 2) later set zipped sas dataset in datastep/procedure.

is possible? if please alter code below, do:

libname lib "path"; filename txtfile pipe "gzip -dc filepath";  data lib.ds1; **would zipped sas dataset**;     infile txtfile dlm="|" missover dsd;     input *columns*; run; data lib.ds2; **would zipped sas dataset**;     set lib.ds1; *setting zipped sas dataset; run;

try executing gzip command sas session.

data _null_;   command = 'gzip -c /path/ds2.sas7bdat > /path/ds2.sas7bdat.gz';   call system (command); run;

for testing purposes, keep -c option. way can keep original file , compare newly compressed one.

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
