You can specify all rows or columns by using the colon operator, in this case specifying all columns. The elements do not have to be contiguous, such as row 1, columns 1 and 3. You can specify a range of rows and columns to access sections of an array such as row 1, columns 1 through 2. Here is the element of A in the first row second column. You can specify elements of an array by simple row and column indexing. Let's now look at how you can access and change the values of array elements with different forms of indexing. It can be more convenient to inspect the contents of an array by opening it into the variable editor. You can also call a number of functions that generate elementary matrices with different contents such as ones, zeros, or random numbers. You can change the rows to columns with the transpose operator. The linspace space function is similar to the colon operator, letting you specify a start and end value but gives control over the number of points such as 7. You can create equally spaced one dimensional arrays with a column operator such as A equals 1 to 10, A equals 1 to 10 in steps of 2, or A equals 10 to 1 in steps of negative 2. You can create an array by specifying specific values using square brackets and commas or spaces to separate columns in a row such as A equals 1, 2, 3, 4 and semicolons to separate rows. With the MATLAB language, you can create arrays, access and assign values to array elements using a number of indexing methods, and perform many other operations to manipulate the array's contents. So working with arrays is fundamental to working with MATLAB. This includes not only numeric data, but data of other types such as strings or even complex objects. This option is enabled only if you select Customize as the value of the Output dimensionality parameter.MATLAB stores all types of data in arrays. Output dimensions Specifies a custom output dimensionality. Output dimensionality The dimensionality of the output signal. The Reshape block accepts and outputs signals of any data type, including fixed-point data types, except int64 and uint64. For matrices, the conversion is done in column-major order. The number of elements of the input signal must match the number of elements specified by the Output dimensions parameter. The value of the Output dimensions parameter can be a one- or two-element vector. For matrices, the conversion is done in column-major order.Ĭonverts the input signal to an output signal whose dimensions you specify, using the Output dimensions parameter. For matrices, the conversion is done in column-major order.Ĭonverts a vector or matrix input signal to a row matrix, i.e., a 1-by-N matrix where N is the number of elements in the input signal. (This option leaves a vector input unchanged.)Ĭonverts a vector or matrix input signal to a column matrix, i.e., an M-by-1 matrix, where M is the number of elements in the input signal. The output vector consists of the first column of the input matrix followed by the second column, etc. The Output dimensionality parameter lets you select any of the following output options.Ĭonverts a matrix (2-D array) to a vector (1-D array) array signal. For example, you can use the block to change an N-element vector to a 1-by-N or N-by-1 matrix signal, and vice versa. The Reshape block changes the dimensionality of the input signal to a dimensionality that you specify, using the block's Output dimensionality parameter.
