I would expect k to be a column vector of length size (A,1) with the i-th element of k giving the desired column index. Right now, I'm just using find () on each row inside of a for-loop:Dec 10, 2013 · For example, if you use fewer colons than there are dimensions in the array (like above), MATLAB will automatically concatenate the remainder of the data along the dimension equal to the colon count. So, if A has 48 dimensions, but you index with just 2 colons: you'll get a 2D array, that is the concatenation of the remaining 46 dimensions ... MATLAB indexed assignment rules apply to size specifications. For example, a 1-by-1 value is compatible with the size specified as (5,3) because MATLAB applies scalar expansion. Also, MATLAB row-column conversion applies so that a size specified as (1,:) can accept a size of 1-by-n and n-by-1. Here are some examples:This MATLAB function concatenates the arrays A1,...,AN along dimension dim.Building a broader south Indian political identity is easier said than done.

As long as the number of elements in each shape are the same, you can reshape them into an array ... All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array. We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some special types of arrays. Special Arrays in MATLABexample. B = prod (A) returns the product of the array elements of A. If A is a vector, then prod (A) returns the product of the elements. If A is a nonempty matrix, then prod (A) treats the columns of A as vectors and returns a row vector of the products of each column. If A is an empty 0-by-0 matrix, prod (A) returns 1. Every array in MATLAB has trailing dimensions of size 1. For multidimensional arrays, this means that a 3-by-4 matrix is the same as a matrix of size 3-by-4-by-1-by-1-by-1. Examples of multidimensional arrays with compatible sizes are: One input is a matrix, and the other is a 3-D array with the same number of rows and columns.Jan 25, 2016 · Copy. k = find (A < 5, 1, 'last', 2); This would say, return the column index (dimension 2) of the last 1 element of each row of A satisfying the condition A < 5.

Name-value pair: If you set this property as a name-value pair with the “plot” function, you must set it after all the x,y pairs. Name-value pair settings apply to all the plotted lines.Jan 1, 2018 · Another method for accessing elements of an array is to use only a single index, regardless of the size or dimensions of the array. This method is known as linear indexing. While MATLAB displays arrays according to their defined sizes and shapes, they are actually stored in memory as a single column of elements. The size controls the area of each marker in points squared. An empty array specifies the default size of 36 points. The way you specify the size depends on how you specify X, Y, and Z and how you want the plot to look. This table describes the most common situations.
