If n is zero or negative then an empty 1x0 If n is not an integer then floor ( n) is used to round When a single value ( n = 1) is requested. Programming Notes: For compatibility with MATLAB, return the right-hand Which is useful in digital signal processing. If the number of elements n is unspecified it defaults to 50. Return a row vector with n elements logarithmically spaced from : y = logspace ( a, b) ¶ : y = logspace ( a, b, n) ¶ : y = logspace ( a, pi) ¶ : y = logspace ( a, pi, n) ¶ If n is zero or negative then an empty 1x0 matrix N is not an integer then floor ( n) is used to round the Programming Notes: For compatibility with MATLAB, return the secondĪrgument ( end) when a single value ( n = 1) is requested. Linspace transforms them to column vectors and returns a matrix whereĮach row is an independent sequence between If one, or both, inputs are vectors, then The linspace function returns a row vector when both start andĮnd are scalars. Number of points n is not specified, a value of 100 is used. Greater than end, the elements are stored in decreasing order. Start and end are always included in the range. If the number of elements n is greater than one, then the endpoints Return a row vector with n linearly spaced elements between start : y = linspace ( start, end) ¶ : y = linspace ( start, end, n) ¶ The functions linspace and logspace make it very easy toĬreate vectors with evenly or logarithmically spaced elements. A row vector is alwaysĬonceptually the result is calculated as follows: Matrix then the columns of x are imagined to be stacked on top ofĮach other for purposes of the selection index. Second row, r(2,j), specifies the repeat count. R is a 2x N integer matrix specifying which elements to repeatĪnd how often to repeat each element. ForĬopying along more than two dimensions, specify the number of times to copyĪcross each dimension m, n, p, …, in a vector in theĬonstruct a vector of repeated elements from x. If n is not specified, form an m by m block matrix. : B = repmat ( A, m) ¶ : B = repmat ( A, m, n) ¶ : B = repmat ( A, m, n, p …) ¶ : B = repmat ( A, ) ¶ : B = repmat ( A, ) ¶įorm a block matrix of size m by n, with a copy of matrix
