FREE Basic MATLAB Introduction Questions and Answers
What is the typical data type in MATLAB for numeric value(s)?
Explanation:
The typical data type in MATLAB for numeric values is a double-precision floating point, also known as "double." This data type represents real numbers with high precision, using 64 bits to store each value. MATLAB also supports other numeric data types, such as single-precision floating-point (float), integer data types (int8, uint8, int16, uint16, int32, uint32, int64, uint64), and complex numbers (complex). However, double is the default data type used for most numerical computations in MATLAB.
All variable names must only contain letters, digits, and underscores ( ).
What MATLAB command should be used to make y = 3(x+2) when x = 2?
If Arr = [9 3 5 7 10 0 16], how big is an array?
Explanation:
The array `Arr` has seven elements, making it a 1x7 array. In MATLAB, the size of an array is given by the number of rows and columns it has. A 1x7 collection has one row and seven columns, meaning it is a row vector with seven elements.
What command in the workspace browser clears all variables?
Explanation:
The clear command in MATLAB is used to remove all variables from the workspace.
Except for the following, all of the next are benefits of MATLAB programming:
What built-in MATLAB constant represents the square root of -1?
Explanation:
The fictitious unit I or j is the pre-defined constant in MATLAB that represents the square root of -1. These constants represent complex numbers in MATLAB.
