How do you find the size of an array in MATLAB?
How do you find the size of an array in MATLAB?
size (MATLAB Functions) d = size(X) returns the sizes of each dimension of array X in a vector d with ndims(X) elements. If X is a scalar, which MATLAB regards as a 1-by-1 array, size(X) returns the vector [1 1] . [m,n] = size(X) returns the size of matrix X in separate variables m and n .
What is cell array in MATLAB?
A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. Cell arrays commonly contain either lists of text, combinations of text and numbers, or numeric arrays of different sizes. Refer to sets of cells by enclosing indices in smooth parentheses, () .
How do you create a cell array in MATLAB?
When you have data to put into a cell array, create the array using the cell array construction operator, {} . Like all MATLAB® arrays, cell arrays are rectangular, with the same number of cells in each row. myCell is a 2-by-3 cell array. You also can use the {} operator to create an empty 0-by-0 cell array.
What is Matlab command size?
For example, if A is a 3-by-4 matrix, then size(A) returns the vector [3 4] . If A is a table or timetable, then size(A) returns a two-element row vector consisting of the number of rows and the number of table variables. [ sz1,…,szN ] = size(___) returns the lengths of the queried dimensions of A separately.
How do I create an array of zeros in Matlab?
X = zeros( sz ) returns an array of zeros where size vector sz defines size(X) . For example, zeros([2 3]) returns a 2-by-3 matrix. X = zeros(___, typename ) returns an array of zeros of data type typename . For example, zeros(‘int8’) returns a scalar, 8-bit integer 0 .
How do you turn a cell array into a matrix in Matlab?
A = cell2mat( C ) converts a cell array into an ordinary array. The elements of the cell array must all contain the same data type, and the resulting array is of that data type. The contents of C must support concatenation into an N-dimensional rectangle.
How do I write a cell array to a text file in Matlab?
You can export a cell array from MATLAB® workspace into a text file in one of these ways:
- Use the writecell function to export the cell array to a text file.
- Use fprintf to export the cell array by specifying the format of the output data.
