result_40.txt

在 MATLAB Online 中打开

Hi,

The following code opens a file (named "Pulse.acc") and writes c, s and t values as follows:

0 1 0

0 2 0

0 3 0

It also opens another file (named :Case.tcl") and writes each case number.

Each case over-writes the previous one.

I am now trying to import the values of s from the attached file (named "result_40.txt"). This file contains 40 columns and 10 rows. Each value in the columns will be printed in "Pulse.acc" file and excute OpenSees software model (along with c and t values. For example: 0 1 0, as shown above). This needs to continue until the 10th value in the column. Then, the second column starts.

The values of c and t will continue to be zero, so they could be left as below.

It would be great if a folder can be opened for the outputs from each column and numbered sequentially.

I hope I could explain what I want clearly, and please feel freel to let me know if I need to explain it further.

c=[0 0 0];
s=[1 2 3];
t=[0 0 0];
for j = 1:3
    fidP = fopen('Pulse.acc','w+');
    fidC= fopen('Case.tcl','w+');
    
    fprintf(fidP, '%d\n%d\n%d',c(j), s(j), t(j));
    fprintf(fidC, 'set case %d',j);
    
    fclose(fidP);
    fclose(fidC);
    
    !OpenSees Model.tcl
end
