I am having troubles trying to write a mix of char and numbers to a delimited file.
that dlmwrite cannot handle both char and num and must use a cell array and thus dlmwrite treats each char as a separate element and places a delimiter between each char and number.
basically what i am doing is reading in a large csv files with mix of char and numbers and sorting through the file line by line and only copying the lines that are for the same location (based on a unique id code) to a new file. the data is a mixed bag of temp for all the met stations in tanzania.
example line from my data: "TANZANIA,UNITED REPUBLIC OF",TZ03MSKR,,MUSEKERA,-9.3,33.6,12,1/1/1943,139
once found, i want to copy the exact line to a new file. most importantly i need to append each line to the existing file as my original file is for 35+ years of monthly readings for each 129 different stations.
i got everything working except the append part.
essentially its the same problem as this
filename = 'C:\test.txt';
str = 'test123';
dlmwrite(filename, str, '-append')
returns
t,e,s,t,1,2,3
i was wondering if anyone can help point out a workaround that is different from the quoted thread or is this the best method?
Thanx.
