GM = readmatrix ('file1'); [rowGM, colGM] = size (GM);One way to assign or add a row to a table is to assign a cell array to a row. If the cell array is a row vector and its elements match the data types of their respective variables, then the assignment converts the cell array to a table row. However, you can assign only one row at a time using cell arrays. Assign values to the first two rows.For example, reshape(A,[2,3]) reshapes A into a 2-by-3 matrix. sz must contain at least 2 elements, and prod(sz) must be the same as numel(A). example.

For example, specify that each call to the read function reads three rows of data by calling arrds =.If a cell contains an array, you can access specific elements within that array using two levels of indices. First, use curly braces to access the contents of the cell. Then, use the standard indexing syntax for the type of array in that cell. For example, C{2,3} returns a 3-by-3 matrix of random numbers.The problem is that cell arrays do not allow indexing which means that I cannot use these to subtract data from other cell arrays. So what I want as output is an array that allows indexing such that I can use that array to subtract information of other cell arrays. What I have tried: I have tried str2double to create rows that allow indexing.C = cat(dim,A,B) concatenates B to the end of A along dimension dim when A and B have compatible sizes (the lengths of the dimensions match except for the operating dimension dim ). example. C = cat(dim,A1,A2,…,An) concatenates A1, A2, … , An along dimension dim. You can use the square bracket operator [] to concatenate or append arrays.Jan 19, 2014 · Use the following. A = [A elem] % for row array. or. A = [A; elem] % for col array. Edit: Another simpler way is (as @BenVoigt suggested) to use end keyword.

C is a 2-by-3 cell array.. You also can use the {} operator to create an empty 0-by-0 cell array.The cell arrays for value2 and value3 are 1-by-2, so s is also 1-by-2. Because value1 is a numeric array and not a cell array, both s(1).f1 and s(2).f1 have the same contents. Similarly, because the cell array for value4 has a single element, s(1).f4 and s(2).f4 have the same contents.Concatenate Structures. This example shows how to concatenate structure arrays using the [] operator. To concatenate structures, they must have the same set of fields, but the fields do not need to contain the same sizes or types of data.

What I want is a single struct with field names from the cell array. That said, you are probably right, there is probably a way of doing this with cell2struct. I'll look deeper into it. -Algorithms. When concatenating an empty array to a nonempty array, vertcat omits the empty array in the output. For example, vertcat([1; 2],[]) returns the column vector [1; 2]. If all input arguments are empty and have compatible sizes, then vertcat returns an empty array whose size is equal to the output size as when the inputs are nonempty.Concatenate Structures.
