Does Matlab have lazy evaluation?

Conclusions. The stream programming is a powerful technique to manage infinite sequences of elements, the lazy evaluation allows to manage this particular entities easily, this implementation of streams in Matlab does not look at computational complexity but an efficient version can be implemented.

What is applicative order evaluation?

Applicative order evaluation is an evaluation strategy in which an expression is evaluated by repeatedly evaluating its leftmost innermost reducible expression. This means that a function’s arguments are evaluated before the function is applied.

What is the difference between eager evaluation and normal order evaluation?

As far as I know, eager evaluation/applicative order evaluates all arguments to a function before applying it, on the other hand, lazy evaluation/normal order evaluates the arguments only when needed.

Does C have lazy evaluation?

The C/C++ operators ||, &&, and ? : are both examples of lazy evaluation. Yes, but you can do ContinuationPassingStyle transformation in a lazily evaluated language to force strict evaluation; and you can lift all expressions into subfunctions in a strict language to get lazy / normal-order evaluation.

What is the point of lazy evaluation?

The benefits of lazy evaluation include: The ability to define control flow (structures) as abstractions instead of primitives. The ability to define potentially infinite data structures. This allows for more straightforward implementation of some algorithms.

Which language has call-by-name as default?

Call by Value vs. Call by Reference

Does scheme use normal order or applicative order for evaluation?

, where we began our discussion of models of evaluation, we noted that Scheme is an applicative-order language, namely, that all the arguments to Scheme procedures are evaluated when the procedure is applied.

What type of value is passed to the eval function?

Answer: eval is a built-in- function used in python, eval function parses the expression argument and evaluates it as a python expression. In simple words, the eval function evaluates the “String” like a python expression and returns the result as an integer.

Why is lazy evaluation bad?

The cost/benefit of using lazy evaluation decreases as the item being accessed becomes less likely to be accessed. Always using lazy evaluation also implies early optimization. This is a bad practice which often results in code which is much more complex and expensive that might otherwise be the case.
