Interpolating strings in MATLAB is the process of constructing new strings based on a template string and a set of variables that are substituted into the template string. Here is an example of how to interpolate strings in MATLAB:
Suppose we have two variables, name and age, and we want to create a string that says "My name is (name) and I am (age) years old." We can do this using interpolation in MATLAB as follows:
name = 'John';
age = 25;
str = sprintf('My name is %s and I am %d years old.', name, age);
disp(str);
This will output the following string:
My name is John and I am 25 years old.
In this example, the %s and %d placeholders are used to indicate where the values of name and age should be inserted in the template string. The sprintf function is used to perform the interpolation and create a new string.
Another way to interpolate strings in MATLAB is to use the curly brace notation {}. Here is an example of how to do this:
name = 'John';
age = 25;
str = ['My name is ', name, ' and I am ', num2str(age), ' years old.'];
disp(str);
This will output the same string as before:
My name is John and I am 25 years old.
In this example, the variables name and age are concatenated using the square bracket notation []. The num2str function is used to convert the numeric value of age to a string so that it can be concatenated with the other string elements. The curly brace notation {} is used to insert the values of name and age into the template string.
