Matlab width of matrix

Help Center Help Center. For vectors, the length is simply the number of elements.

Help Center Help Center. The number of rows and columns in obj. The number of rows in obj , or the length of the dimension specified by dim. The length of the first N dimensions of obj. For example, size obj,1 returns the number of rows.

This command find the size of the maximum dimension of x. To compute the sum matrix, use the command sum x. If dim is equal 1, z will sum up by rows while if it is equal 2 by columns. To find the minimum element of a vector or the rows of a matrix, use the command min x. If x is a vector, min x is scalar otherwise if it is a matrix use dim as usual. To sort the values of a vector or the rows of a matrix from smallest to largest, use the command sort x. The complete command,. To take the exponential of a vector or matrix element by element , use exp. To compute the sample variance of a vector or a matrix, If x is a vector, var x is scalar. If x is a matrix, var x is a K by 1 vector containing the sample variances of each column. Note: This command uses T — 1 in the denominator unless an optional second argument is used. To compute the sample covariance of a vector or matrix, use the command.

No, overwrite the modified version Yes. For an example, see Size of 4-D Array.

Help Center Help Center. 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. You can also specify dim as a vector of positive integers to query multiple dimension lengths at a time. For example, size A,[2 3] returns the lengths of the second and third dimensions of A in the 1-by-2 row vector szdim. You can query multiple dimension lengths at a time by specifying a vector dimension argument. For example, find the lengths of the first and third dimensions of A. Find the size of the table. Although the BloodPressure variable contains two columns, size only counts the number of variables. Input array, specified as a scalar, a vector, a matrix, or a multidimensional array.
