I am trying to use Ace Ventura's 3D frame analysis matlab file, but couldn't figure out how to create the input files 11, 12 and 13 for the nodal coordinates. The .m file doesn't seem to contain or explain how to create these input files and their format. Thanks.

Hi Raghu,

The input data files 11, 12 & 13 should contain joint x,y and z coordinates respectively. Each file should list only one coordinate per joint in the order of the joints.

Regarding the format, if you open the file 'frame3d_6j.m' provided here - https://in.mathworks.com/matlabcentral/fileexchange/49559-structural-analysis-of-3d-frames , you will see that the data files 11, 12, & 13 are text files with the extension '.TXT'. So, you may rename all the files to 'inputdata11.txt', 'inputdata12.txt' and 'inputdata13.txt' as described in the given MATLAB code itself.

Also, you may place the files in the directory where your MATLAB script is located, or specify the path to the file within the script if necessary.

Hope it helps!
