WebIn Mathematica, we input each instruction and press the “return” key. After all instructions are typed in, we press the “enter” key to execute the sequence. Individual instructions in the code can be assignment statements, iteration statements (loops), conditional (if), input or output statements, functions, or other programming constructs.

Web27 de nov. de 2024 · This is the only thing that makes sense in a math (not programming) context. Therefore Piecewise has a numerical default value. Similarly, Which holds its arguments unevaluated. You can safely write Which [x > 0, Print@Sqrt [x]], and trust that Print won't be evaluated until the condition is true. WebMathematica will be considerably faster and more powerful if you do that. Useful functions are Map[], and related functions. Also Nest and NestList will repeat operations. Many functions like RandomVariate will naturally produce a list of samples. (which can then be processed as a list and not used in a loop). I hope this helps. Regards
