Round function example: if you take the number 4.3, round will output 4, but if you use the number 4.6, the round function will output 5.In short, this will round to the nearest integer for negative and positive values. Round to the nearest integer for positive and negative values: if you want to round a number to its nearest integer value in MATLAB, you need to use the round function.Round to the Nearest Integer: Round Function Round down using the floor and fix functions.Round to the nearest Integer using the round function.To sum up, you can round down, up, to the nearest integer, and to X decimal places using the floor, ceil, fix, and round MATLAB functions. In this article, we will tackle the different ways to round numbers in MATLAB.

Here we discuss the Introduction to MATLAB Indexing and its different Examples as well as its input and output.Start Your First Python Project in 3 Steps : Grab Your Free Online Course Right Now! As an additional feature, indexing can also be used to compare values of arrays. We can use indexing to obtain the value present at any desired location in an array. In this article, we have learnt how the indexing works in MATLAB. For the values in ‘X’, which are greater than ‘Y’, the output array has a ‘0’.

0 showing value in X is not less than Y at that particular cell and 1 showing that value at X is less than Y.Īs we can clearly see in the output above, we have obtained a ‘1’ for all values in ‘X’ which are less than corresponding values in ‘Y’. X = Y = We will pass the condition X < Y, to find out the elements in X, which are less than elements in Y.The output, in this case, will be an array of 0s and 1s. In the scenario where we want to know which all elements of an array X are greater than or less than another array Y, we can use this feature of indexing.Īll we need to do is pass the ‘’ sign between these 2 arrays as per our requirement. Let us understand how this can be achieved. It is also possible to index arrays based on logical operators. So, if we need all the elements of 4 th row, we just need to pass.

Example #4Īnother way of using the index is to access all elements of a particular row or column.įor this, we will pass just the row or column number whose elements we require. The output is an array with 1 st, 2 nd, and 3 rd row selected, with elements from the 2 nd and 3 rd columns.

In the next scenario, let us assume that we need to get elements from the 1 st row till the 3 rd row, and from the 2 nd column till the 3 rd column.įor this purpose, we will specify the index range that we are looking for and will separate row and column ranges by a ‘colon’. All we did is passed the indices of required elements with the help of a vector to MATLAB. For our understanding, let us try to get the 3rd and 4th element of 3rd row.Īs we can clearly see in the output, we are able to get the 3 rd and 4 th elements of the 3 rd row, i.e, 11 and 2. We will use the same array as above for this example. Let us now take the scenario where we want to reference more than one element of a row. 7 is selected from the input array Example #2 X = Īs we can clearly see in the output, only the value present at position (2, 3), i.e. This is how our input and output will look like in MATLAB console: The Output that we obtain will be a single value present at the position (2, 3) in the array X. The Syntax that we will use in MATLAB is:
