| Version | Published | Release Notes | Action |
|---|---|---|---|
| 3.21.0 | Minor syntax and code commentary edits |
||
| 3.20.0 | Implemented an option to use the so-called "Modified Newton-Raphson" method (constant stiffness) and wrote script that is similar to Chopra's Example 5.6. |
||
| 3.12.0 | more flexibility for regression testing |
||
| 3.11.0 | Slightly refactored testing script again |
||
| 3.10.0 | enhancements to regression testing script |
||
| 3.1.0 | Reverting a couple lines of code that are not compatible with some recent version of MATLAB |
||
| 3.0.0 | Major updates to all codes; implemented data format validation of function inputs; simplified input file syntax; developed Fourier transform function & applied it to automatic time-step selection; fixed round-off error bug in 'generate1DGridPoints()' |
||
| 2.30.0 | created a regression testing system |
||
| 2.20.0 | Added Example 5.4 from A.K. Chopra to demonstrate the linear elastic case. Also, edited some misleading commentary |
||
| 2.11.0 | I think something went wrong in the update... trying again. |
||
| 2.10.0 | V2 update: most of the calculations have been placed in a MATLAB function script. This way, the main files are more focused on inputs and the workspace gets populated with only nontrivial data. |
||
| 2.3.0 | New image. |
||
| 2.2.0 | Made edits to the public description. |
||
| 2.1.0 | Quick syntax formatting. |
||
| 2.0.0 | Version 2.0 introduces significant improvements to the overall solution procedure and code format. The algorithm used has deviated some from A.K. Chopra's and execution is now based on a broader and more well defined set of input parameters. |
||
| 1.0.1 | Just needed to edit the description. Did not change the code. |
||
| 1.0.0 |
