A look ahead.

I previously posted that I wanted to add matrices, derivatives, and approximate definite integrals in the next release or couple of releases.  The last release included matrices.  As you can guess, the next one will include derivatives and approximate definite integrals.  So what does approximate definite integrals mean?  Well, it means that while in decimal mode, definite integrals can be simplified to an approximate decimal value.  Integrals will not me simplified in integer mode (since the calculator won't have the ability to compute anti-derivatives to get the exact result).

I do hope to add the ability for the calculator to attempt to compute anti-derivatives, and therefore be able to compute indefinite integrals (which is the same thing as anti-derivative) and exact answers, in integer mode, for definite integrals.  However, this will take a lot of work to write.  This won't be added anytime soon, and I can't say for sure it will ever be added.  If it is added, expect it for the Pro version only.

The last release included matrices.  Some matrix operations were added, however, there will be more added in the future.  They won't be coming in the next release, but should be added in the next few releases.  Here is a list of what I am hoping to add for matrices:

  • Cofactor Matrix
  • Reduced row echelon form
  • LUP decomposition
  • QR decomposition
  • Eigenvalues and Eigenvectors

These additional matrix features will likely only be added for the Pro version.
