How do you convert a number to an integer?

In Java, we can use Integer.valueOf() and Integer.parseInt() to convert a string to an integer.

  2. Use Integer.valueOf() to Convert a String to an Integer. This method returns the string as an integer object.

What is num2str?

s = num2str( A ) converts a numeric array into a character array that represents the numbers. The output format depends on the magnitudes of the original values. num2str is useful for labeling and titling plots with numeric values.

How do you assign data types in MATLAB?
