4 The function ndims returns the number of dimensions of an array: >> f=ndims(A) f = 2 The function size returns the number of rows and columns of an array: >> g=size(A) g = 4 3. 4.4 Indexing . Most of the data used in Matlab consists of vectors and arrays and at times only a subset of numbers are of interest. This is where indexing becomes ...

Each element in a vector has an address, also called an index . Indexing starts at 1 (not 0) in MATLAB. We can access/retrieve/extract the individual elements by referring to their addresses. Useful for transforming data or doing calculations with only part of a vector. Vector functions (Instructor’s In …

If not stated otherwise, all vectors in MATLAB are indexed starting from 1, e.g., x( 1) is the first element of vector x. Thus, in order to represent a signal with negative or zero time index, an additional index vector should be defined. The following code will define a discrete-time signal x[n]=2n, for n …

Thus, we cannot use a matrix to hold this data. Fortunately, MATLAB has a data structure that is well suited for this purpose. It is called a cell array. Unlike the rows of a matrix, each element in a cell array can hold something totally different. In this case, each element in the cell array holds the spike times for each run of the movie.
