The goal of my code is to take an n-by-n logical array of values and output a cell vector containing the column indices of each true (1) element in the input matrix. Technically, a logical array is represented internally the same as a uint8 array of ones and zeros (one byte per element, set to 0x00 or 0x01). MathWorks is the leading developer of mathematical computing software for engineers and scientists. Every variable in MATLAB is an array that can hold many numbers. Array Indexing In MATLAB, there are three primary approaches to accessing array elements based on their location (index) in the array. If you want to slice a cell-array, use parentheses. To access the last element of an array stored in cell array C at location {m,n}, y = C {m,n} (end); To access the last element of all cells stored in cell array C, y = Every variable in MATLAB is an array that can hold many numbers. A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. For example, return a numeric vector from the cell that contains it.

I am trying to index from cell array, but I am getting Unable to use a value of type cell as an index. Based on Array Indexing In MATLAB, there are three primary approaches to accessing array elements based on their location (index) in the array. You can also select a web site from the following list: Select the China site (in Chinese or English) for best site performance. Choose a web site to get translated content where available and see local events and A cell array is a data type with indexed data containers called cells, where each cell can contain any type of data. If you omit the middle step, as in start:end, MATLAB uses the default step value of 1.
