The following Matlab project contains the source code and Matlab examples used for compute relative error between n-dimensional arrays. . Finding the relative error between arrays can be useful, for instance, in determining whether an iterative function is converging to the correct solution.

The following Matlab project contains the source code and Matlab examples used for min max for arrays. Gives minimum or maximum value and its indices [row column] for a 2D array. For a vector works same as regular min and max.

The following Matlab project contains the source code and Matlab examples used for displays vectors, matrices and 3d-arrays using custom data formats, elements separators and brackets . function row = disparray(array, format, separator, brackets_type) % DISPARRAY - Displays arrays using a custom format % % This function displays scalars, one-dimentional arrays (vectors), % two-dimentional arrays (matrices) and three-dimenational arrays, % using customized format, elements separator and brackets type % % INPUTS: % array: a scalar, a vector, a matrix or a 3D-array

The following Matlab project contains the source code and Matlab examples used for multi dimensional matrix product, outer product and partial trace. This set of 3 files is aimed at efficiently extending matrix multiplication to higher dimensional arrays.

The following Matlab project contains the source code and Matlab examples used for automatically arranged multiple subscripts from linear index. sub = ind2sub1(siz, ind)   Multiple subscripts (written into one vector or matrix) from linear index "ind" for an N-dimensional array defined by its array size "siz".

The following Matlab project contains the source code and Matlab examples used for index create a list of the indices and values of an array. This function displays each value of an array together with its index.

The following Matlab project contains the source code and Matlab examples used for append a new entry to structure array, fields don't need to be same. This is quite handy for me as I could not deal with MATLAB's requirement of having _exact_ same fields in structure arrays if you want to work with the structure outside the array and then append/insert it back in.

The following Matlab project contains the source code and Matlab examples used for returns unique elements in an array and all the indices for the repetitious values. . [B P]=numunique(A) for the array A returns the same values as in A but   with no repetitions.

The following Matlab project contains the source code and Matlab examples used for crop arrays with axis-aligned minimum bounding box . Often I have to extract a subset of a two-dimensional array for further analysis.

The following Matlab project contains the source code and Matlab examples used for an array that inherits from class double and allows a user to index elements using an enumerated typ . ENUMARRAY inherits from class double, but allows a user to index into the array using enumerated indices (i.

The following Matlab project contains the source code and Matlab examples used for howmany counts occurrencies of numbers in array. % [val, num] = howmany(x) % % counts the number of occurrences of finite values in x % % in: x vector of nnumbers (array will be reshaped to a vector) % % out: val unique values in x, sorted % num number of occurrences.

The following Matlab project contains the source code and Matlab examples used for split a 2d array into equally-sized sub-arrays. . A = tile(B,nx,ny,overlap) input: B = 2D array nx = number of tiles in column direction ny = number of columns in row direction overlap = ammount of overlap of tiles in pixels %OUTPUT A = cell array of size ny by nx with each cell containing a tile.
