isKey

---

Check if dictionary contains key

---

Syntax

---

tf = isKey(d)

Input argument

---

d

scalar: dictionary object.

Output argument

---

tf

scalar logical: true if key, false if not.

Description

---

tf = isKey(d, key) returns a logical true if the specified key exists in the configured dictionary, and a logical false if it does not.

If d is an unconfigured dictionary, isKey throws an error.

If key is an array of multiple keys, then tf is a logical array of the same size.

Example

---

names = ["Biil" "John" "Yann"];
wheels = [1 2 3];
d = dictionary(wheels, names)
tf = isKey(d, "John")
tf = isKey(d, ["biil" , "Yannis")
