ELSEIF or ELIF in mathematica? - Online Technical.

If is a procedural programming structure whose evaluation branch is determined by the truth value of a specified condition. If typically takes a condition plus two additional arguments: If ( cond, t, f ). Here, t and f are evaluated if the condition is True or False, respectively.

Tests and Conditionals: Elementary Introduction to the.

Update the question so it's on-topic for Mathematica Stack Exchange. Closed 4 years ago. What I am wondering is how do you perform multiple lines when using the If statement.The Wolfram Language's symbolic character allows a powerful unification of the notion of conditionals in programming and in mathematics.Switch(expr, form1, value1, form2, value2, .) evaluates expr, then compares it with each of the formi in turn, evaluating and returning the valuei corresponding to the first match found.


Which(test1, value1, test2, value2, .) evaluates each of the testi in turn, returning the value of the valuei corresponding to the first one that yields True.Testing Expressions Wolfram Language symbolic expressions can represent an immense range of types of objects. The Wolfram Language provides a rich collection of functions to test expressions.

Create tests in the Wolfram Language. Learn to find equality, parity, logic. Also, test for words, images, distance. Written by Stephen Wolfram.

Which is essentially a replacement for nested If statements. Switch in Mathematica resembles Switch in C, but differs from it significantly. First, it has a different (extended in a sense) functionality since it works on patterns (patterns are extremely important. We will cover them later).

If Statement In Mathematica

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.

ADSW121365 - the conditions for the if statement look fine. I just don't understand how the elseif conditions relate to the Mathematica equation that you have shown (which only references Sign(y) and not Sign(x)). And is the data in the mat-file the same data used for the Mathematica plot?

This answer is not intended to show the most efficient method, but rather an alternative method that serves the pedagogical purpose of showing some important core functionality in Mathematica. nixeagle's answer avoids explicitly testing every element of the list. If the test doesn't lend itself to inclusion in the third argument of Select, then the below might be useful.

If Statement In Mathematica

Using the sign(y) like I did reproduces the Mathematica statement. If the Mathematica is correct, then the code I posted is correct and the code you posted using sign(x) is not correct. Conversely, if you find that you need sign(x) to get the plot you were interested in, then the implication is that the Mathematica posted is not correct.

Other answers explain why the first option is normally the best. But if you have multiple conditions, consider creating a separate function (or property) doing the condition checks in option 1.

If Statement In Mathematica

Ending with a semicolon tells Mathematica not to show the output. This rule applies to all Mathematica inputs. (Sometimes the output is quite lengthy and one does not want to see it printed on the screen.) Built-In Functions. Mathematica has many built-in functions that are familiar from calculus: sinx, cosx, expx, logx, to name but a few.

Note: Mathematica generally ignores carriage returns, extra spaces, tabs, etc. Therefore, you should include them as necessary in order to make your code more readable. Evaluate the cell containing the If statement ten times, keeping track of how many times a match is made and record your results.
