So,in this article we learnt, size function can be used to calculate size of any array in MATLAB. In such cases, the last variable will be the product of all remaining dimensions.So, in our case, the product of last two dimensions is collapsed to last variable.Īs we can observe in the output, the last variable contains product of 3 and 2, which are size of last 2 dimensions. Next, let us take the example when our output variables are less than ndims (Y). Here also, we will use the same array as in the above exampleĪs we can see, the input has 3 size dimensions, but our output variables are only 2. To get size of the dimension, below is our code: Here, we are creating 2 arrays of size 4 x 3, with all ‘unity’ elements.
Let us first define a different input array.
To assign sizes of dimensions to separate variables, we can use below code:Īs we can observe in the output, we have got size for all dimensions in separate variables.
To find out the size of third dimension, this is how our input will look like in MATLAB:.Let us first define our input array as: rand(2, 4, 5)Īs we can see in our input, the size of the third dimension in rand(2,4, 5) is 5.Let us try to find the same with the help of ‘size’ function. Now let us understand the computation of size in MATLAB with various examples: Examples to Implement Size Function in MATLABīelow are the examples Size Function in MATLAB: Example #1 ‘dn’ will contain the product of sizes of remaining dimensions of Y The function will return those present in the extra variable In case the number of arguments ‘n’ in output are not equal to ndims(Y), then if: n > ndims(Y) = size(Y), this function will return the size of ‘n’ dimensions of input array X in separate variables.A = size(Y,dim), this function will return the size of Y’s dimension, specified by the input scalar dim.= size(Y), this function will return the size of input matrix in 2 separate variables ‘a’ and ‘b’.A = size(Y), this function will return the size of each dimension of the array passed as input.= size(Y) Description of Size Function in MATLAB Hadoop, Data Science, Statistics & others
