Make a loop
I would like to use a loop to simplify the belows. Is there anyone to let me know how?
Dividing 6*m*n array into 6 m*n matrices. Then after transposing 6 matrices, save them as xlsx file.
I'd appreciate it.
fac2group1 = arraytomat(fact2Final[1,.,.]);
fac2group2 = arraytomat(fact2Final[2,.,.]);
fac2group3 = arraytomat(fact2Final[3,.,.]);
fac2group4 = arraytomat(fact2Final[4,.,.]);
fac2group5 = arraytomat(fact2Final[5,.,.]);
fac2group6 = arraytomat(fact2Final[6,.,.]);
xlswritem(fact2group1, "fact2group1.xlsx", "a1", 1, "");
xlswritem(fact2group2, "fact2group2.xlsx", "a1", 1, "");
xlswritem(fact2group3, "fact2group3.xlsx", "a1", 1, "");
xlswritem(fact2group4, "fact2group4.xlsx", "a1", 1, "");
xlswritem(fact2group5, "fact2group5.xlsx", "a1", 1, "");
xlswritem(fact2group6, "fact2group6.xlsx", "a1", 1, "");
Here is some code that will do what you ask and will continue to work if you increase the first dimension of the array to more than six.
//get dimensions of 'fact2Final' orders = getOrders(fact2Final); //First element will contain number //of matrices in the 3D array num_mats = orders; for i(1, num_mats, 1); //Add transpose to assignment step fac2_mat = arraytomat(fact2Final[i,.,.])'; file_name = "fac2group" $+ ntos(i) $+ ".xlsx"; xlsWriteM(fac2_mat, file_name, "a1", 1, ""); endfor;
Or if you wanted to condense it a bit, you could make it short like this:
orders = getOrders(fact2Final); for i(1, orders, 1); xlsWriteM(arraytomat(fact2Final[i,.,.])', "fac2group" $+ ntos(i) $+ ".xlsx", "a1", 1, ""); endfor;
Hello. Thanks a lot. But an error came out, saying ntos is undefined symbol.
Oh, yes. ntos is a new convenience function in GAUSS 14. You can replace:
cvtos(ftocv(i, 0, 0));
for versions older than GAUSS 14.
