Use cell arrays for heterogeneous data that is best referenced by its location within an array. You can create a cell array in two ways: use the {} operator or use the cell function. When you have data to put into a cell array, use the cell array construction ...

Description. C = A.*B multiplies arrays A and B by multiplying corresponding elements. The sizes of A and B must be the same or be compatible. If the sizes of A and B are compatible, then the two arrays implicitly expand to match each other. For example, if one of A or B is a scalar, then the scalar is combined with each element of the other array.

The natural logarithm function in MATLAB is log(). To calculate the natural logarithm of a scalar, vector or array, A, enter log(A). Log(A) calculates the natural logarithm of each element of A when A is a vector or array.Represent Text with String Arrays. You can store any 1-by- n sequence of characters as a string, using the string data type. Enclose text in double quotes to create a string. str = "Hello, world". str = "Hello, world". Though the text "Hello, world" is 12 characters long, str itself is a 1-by-1 string, or string scalar.Keep in mind that the number of elements in the resulting arrays includes the end points. In the above examples, the difference between array element values will be 9/19 , or a little less than 0.5 (unlike the sample array in the question).Add a comment. 2. Keep in mind that matlab starts numbering from 1. Then, useful functions are. zeros (m,n) % Makes a 2D array with m rows and n columns, filled with zero ones (m,n) % Same thing with one reshape (a , m , n) % Turns an array with m*n elements into a m,n square. The last one is useful if you construct a linear array but then …Description. u = repelem (v,n) , where v is a scalar or vector, returns a vector of repeated elements of v. If n is a scalar, then each element of v is repeated n times. The length of u is length (v)*n. If n is a vector, then it must be the same length as v. Each element of n specifies the number of times to repeat the corresponding element of v.

1. If you want to gather the individual (possibly overlapping) neighborhoods into an array so that you can process each neighborhood individually, you can use IM2COL. If you want to create a 'halo' around each element to easily capture all candidate regions, so that overlaps are not counted twice, you can use IMDILATE.An array in MATLAB is really just a vector of elements, strung out in memory. MATLAB allows you to use either a row and column index, or a single linear index. For example, A = magic(3) A = 8 1 6 3 5 7 4 9 2 A(2,3) ans = 7 A(8) ans = 7 We can see the order the elements are stored in memory by unrolling the array into a vector.To create arrays with the same number I'd personally just set a variable and put it in the linspace function.

You can create a multidimensional array by creating a 2-D matrix first, and then extending it. For example, first define a 3-by-3 matrix as the first page in a 3-D array. A = [1 2 3; 4 5 6; 7 8 9] A = 3×3 1 2 3 4 5 6 7 8 9 Now add a second page. To do this, assign another 3-by-3 matrix to the index value 2 in the third dimension.

You either need to use cells (which are basically arrays where each element only contains a pointer to some data, and that "some data" can well be a string) as proposed by Amro; or you need to use a 2-D char array as proposed by b3 (with the caveats discussed below Amro's answer ;-) ). - Jonas Heidelberg Aug 22, 2011 at 18:01 Add a comment

Solution 1: In fact it is possible to have dynamic structures in Matlab environment too. However, it is not a native Matlab structure.
