Try to reproduce this, please. This is the attached file bug.sm (5kb) downloaded 19 time(s).Now, disable the function definition f(x) vectorized will get stuck. Regards, Radovan |

I think Radovan just wanted to indicate a malfunction when the function is disabled and the subsequent vectorization on the function goes into an infinite loop. I think he was expecting a non-evaluation (I was expecting it too)

sergio It does not go into an infinite loop. Once assigned, result of vector/matrix is resident as an identity to the project. No matter if disabled afterwards, calculated and stored. This feature is one of my preferred vs Mathcad. Jean

Vectorizing an image over a function is gorgeous [grayscale, RGB] ... ... but there is an exception ... Explain: Smath vectorizes a matrix over a scalar function.linter, cinter, ainterp are NOT scalar functions.

I'll have to get back to my first postFunction f(x) was not defined. What is going on then? Why the calculation did not stop with an error issued? If you wait enough it can crash SMath. I reproduced that on few computers and suspect this might be a bug or a problem. That was my question. Regards, Radovan |

I reproduced that on few computers and suspect this might be a bug or a problem. That was my question. For sure, if you wait too long before [Shift+Esc] it will crash Smath, because it enters an infinite loop. That answers your question ! bug !When entering an infinite loop there should be an error message/stop calculate. Caution: if you figure you have entered an infinite loop stop,stop,stop ...it will crash Smath and zap the document "root element missing" => 0kB All that from true story ! You can generalize your attempt by defining algorithm style.
