Hi! Is it intended that continue (X.) goes to the next iteration without checking the stack?

The manual says "the loop proceeds with the next iteration, if any" - the "if any" part makes it sound like it should check the stack like the loop usually does, and go the next iteration only if it's truthy. That's the behaviour I'd expect from other languages too - continue means skip the rest of the loop, but do check the loop condition again. It seems like that's not the behaviour in MATL, from some testing:

Without continue

octave:1> matl 'F T X` X# '
/-------
STACK{1} = 

0

-------/

With continue at the end of loop

octave:2> matl 'F T ` X# X.'
/-------
STACK{1} = 

0

-------/
/-------
STACK{1} = 

0

-------/
/-------
STACK{1} = 

0

-------/

(output goes on indefinitely, loop doesn't terminate)

This could be an unrealistic way to shave bytes, but I thought I'd mention it just in case.

In this answer, I noticed an odd pattern:

&*XRXzXM

The final 3 functions were all modified by X. Could it be useful to have something like "enable implicit modifier"? I'll use <M>_ to denote this, seeing as X_, Y_, and Z_ are unused. This answer could become:

&*X_RzM

...saving 1 byte. It is very situational, but maybe common enough to warrant this shorthand. I want to do a bit of a corpus analysis to see if this would do anything useful, similar to lynn's for Jelly

First of all, nice project!

In the introduction I read that one can get started in a few minutes, so I decided to try it a bit, but it is actually not that easy to get started.

When browsing the doc, I see a few examples of MATL code, and their MATLAB equivalent, but without much help on turning MATLAB code into MATL code.

Here is what I tried:

Getting the sum of numbers 2:10

2:10 % This is easy!
sum(2:10) %Hmm too bad
s(2:10) %Well this is the function, now how do I call it
...
2:10s %Yay
Input: 10 code: :s %Ok, so it is easy to use one input
inputs: 2 and 10 code: :s %Ok I guess I don't know how to use two

After this I tried to use datestr, but I basically failed to make it do anything. (First attempt was to replicate a simple datestr(1)).

So my conclusion:
I think this will help a lot for code golf, but a number of examples on how to get from MATLAB to MATL would be very helpful :)

The colon operator should be able to make ascending and descending arrays. For example, this:

4:2

should push the array

[4 3 2]

Rather than just pushing an empty array, like it does now. This is possible right now with:

2:4P

But this way is one byte longer and less intuitive.

Hello,

I'm sorry but couldn't find your email address so I'm asking this favor through an Issue.

I'm trying to learn your language but could not figure out how to create and add numbers to an array.

I've got this program:
`to?3*Q}2/]tq}x@
that prints the number of iteractions to run a collatz conjecture up to 1.
I'd like to modify it so it prints the whole set instead of its length.
