See examples of vertical and horizontal concatenation, scalar expansion, and cell replacement. See more2. A cell array. In this case, you group your images into a cell array, and each image is contained in its own cell. imgCell={image1,image2,image3,...}; This is a good choice (the only choice) when your images are of different sizes. To access each individual image, you can index the cell as follows: image1=imgCell{1};There is no reason why subscript indexing cannot be used to access the contents of a multi-dimensional cell array. If those cells happen to contain more cell arrays, then of course more cell array indexing will be required. And this is true for a scalar cell array, a vector cell array, or even a multi-dimensional cell array: it is unrelated to ...C = vertcat(A,B) concatenates B vertically to the end of A when A and B have compatible sizes (the lengths of the dimensions match except in the first dimension). example. C = vertcat(A1,A2,…,An) concatenates A1, A2, … , An vertically. vertcat is equivalent to using square brackets to vertically concatenate or append arrays.Concatenation of structure arrays requires that these arrays have the same set of fields. So is it possible to add new element with empty fields? UPDATE. I found that I can add new element if I simultaneously add new field: >> a=struct() a = struct with no fields.By transposing the cell array, you turn each cell into a row of the resulting matrix. You can then transpose the matrix to make each cell a column: M = cell2mat (C.').'; Transpose each cell: If each cell contains a column vector, cell2mat can do the job directly. You can use cellfun to handle the looping for you:With MATFILE function(if that works with cell-arrays) if I get it write part of .mat file then i can also read part of a file without loading it. hence all i want is MATFILE to work with cell-arrays if it does. ...
