X = zeros(size(p),'like',p) X = 2x3 uint8 matrix 0 0 0 0 0 0 Get class(X) ans = 'uint8' Clone Distributed Array If you have Parallel Computing Toolbox™, create a 1000-by-1000 distributed array of zeros with underlying data type int8. For the distributed data type, ...
Size of 4-D Array Create a random 4-D array and return its size. A = rand(2,3,4,5); sz = size(A) sz =1×42 3 4 5 Query the length of the second dimension ofA. szdim2 = size(A,2) szdim2 = 3 Query the length of the last dimension ofA. ...
Prototype of array to create, specified as an array. Data Types:double|single|logical|int8|int16|int32|int64|uint8|uint16|uint32|uint64 Complex Number Support:Yes Output Arguments collapse all Array of zeros, returned as a scalar, vector, matrix, or multidimensional array. ...
If the size of any dimension is 0, thenXis an empty array. If the size of any dimension is negative, then it is treated as 0. Beyond the second dimension,Infignores trailing dimensions of length 1. For example,Inf([3 1])creates a 3-by-1 vector ofInfvalues. ...
Here,Zis the output array of sizem-by-nfilled with zeros. The function can also take additional arguments to create arrays with more than two dimensions. For example: Z=zeros(m,n,p,...); This creates a multidimensional array with dimensionsm,n,p, and so on, filled with zeros. ...
