Currently when I run this code it saves the max stress and index as just a variable rather than a matrix of each vector.

But with cells I am unsure how to do it.Ĭount = linspace(1, size(data(k).codes,1), size(data(k). Learn more about cell array, for loop, index MATLAB Hi, I want to extract the index and max value from a cell containing vectors. If these where only numbers I knew how to concatenate/append matrices. Now I just need to append them one below the other and then save to excel. The loop above creates the columns I want. What I am trying to do is to create a big cell with three columns: id count codes where id indexes the element number (1 to 250), count indexes the row of the string and codes are just the codes.Īn example to make it clear: for k = 1:size(data,2)Ĭount = linspace(1, size(data(k).codes,1), size(data(k).codes,1))' The structure has 250 elements and one field called codes (whose dimension varies).Īs an example: data(1).codes is a 300 x 1 cell of strings and data(2).codes is a 100 x 1 cell of strings. k, the fastet way would be to use a pre-allocate a large matrix, say BETA (k,k,p, N) and just index the fourth dimension to populate BETA. If all the Bi had the same number of elements, i.e.k1 k2. Use cell2mat to convert from a cell into a numeric array.I have a structure named data. The problem: I am trying to plan what is the best way to store the Bi matrices to populate the large matrix (of which A0 is just one block). Use num2cell to convert from a numeric into a cell array.Ĭonverting From a Cell Array into a Numeric Array Syntax C char (A) C char (A1. C 'Hello, world' C 'Hello, world' If you have an array of a different data type, you can convert it to a character array using the char function, described below. Uses GUI Tables Ĭell arrays are used when displaying a table to a figure.Ĭonverting to and from cell arrays Converting From a Numeric Array into a Cell Array Creation You can create a character vector using single quotation marks. For example, a queue data structure using the commands:Īn element can be popped from the front of the queue using the commands:Ĭell_array(1)=  % remove first element - resize While cell arrays are a powerful tool, these arrays work differently because each element can be almost anything.Ĭell arrays can be dynamically resized, which is a key feature in more advanced data structures. With fewer limitations for the content of a cell array comes complications. It creates a character array, but its easy to turn that back to numbers. Cell arrays have neither of these limitations.Ĭell_array = How to convert binary value to decimal number in MATLAB. If one element in a regular array is a string then all elements must be a string. The regular array can hold strings however, the string in each element must be the same length. It's like creating an empty canvas and eagerly waiting for your brushstrokes of information. With a single command, you can conjure an empty matrix of cells, ready to be filled with your data. These types of arrays are useful when interacting with spreadsheet software.Ĭreating Cell Arrays Ĭell arrays follow the same conventions as regular arrays except instead of square brackets use curly brackets.Ĭell arrays have fewer limitations than regular arrays. Method 1: The Cell Function One way to summon a cell array into existence is by invoking the mighty cell function. I want to convert it into cell array of Z x 1 ( 500 x 1) where each cell element will be N x M (2 x 100). 1.4.2 Converting From a Cell Array into a Numeric ArrayĬell Array Introduction Ĭell Arrays can contain differing information in every element.1.4.1 Converting From a Numeric Array into a Cell Array.
