How do you round off value in MATLAB?
Y = round( X ) rounds each element of X to the nearest integer. In the case of a tie, where an element has a fractional part of 0.5 (within roundoff error) in decimal, the round function rounds away from zero to the nearest integer with larger magnitude.
How do I format to 3 decimal places in MATLAB?

We use the following rules to round 0.999 to the nearest hundredth: A) If the last digit in the fractional part of 0.999 is less than 5, then simply remove the last the digit of the fractional part.
What does 2DP mean in maths?
2DP – Two Decimal Places.
What is a matrix in MATLAB?
A matrix is a two-dimensional array of numbers. In MATLAB, you create a matrix by entering elements in each row as comma or space delimited numbers and using semicolons to mark the end of each row.
How do you create a matrix in MATLAB with zeros?
Another way to create a matrix is to use a function, such as ones, zeros, or rand. For example, create a 5-by-1 column vector of zeros. MATLAB allows you to process all of the values in a matrix using a single arithmetic operator or function.
What is a multidimensional array in MATLAB?
All MATLAB variables are multidimensional arrays, no matter what type of data. A matrix is a two-dimensional array often used for linear algebra. To create an array with four elements in a single row, separate the elements with either a comma (,) or a space. This type of array is a row vector.
How do I create a matrix or array?
Create a matrix or construct one from other matrices. Access elements of an array by specifying their indices or by checking whether elements meet a condition. Remove matrix rows or columns. Change the shape or arrangement of elements in an existing array. Create and manipulate arrays with three or more dimensions.
