Commented: Image Analyst on 30 Sep Ok so I have this problem here im supposed to complete the sum twice using for loops. I'm new to matlab so the only code i've got no idea where to start. Any help would be appreciated. Adam on 29 Sep Cancel Copy to Clipboard. Answers 2. Walter Roberson on 29 Sep You did not say what sums you had to calculate so I showed how to calculate two different sums in the same for loop. I am going to guess that you are asked to compute the sums for a matrix. In that case. Now suppose you switched the two "for" loops. Image Analyst on 29 Sep

Documentation Help Center. If A is a vector, then sum A returns the sum of the elements. If A is a matrix, then sum A returns a row vector containing the sum of each column. If A is a multidimensional array, then sum A operates along the first array dimension whose size does not equal 1, treating the elements as vectors. This dimension becomes 1 while the sizes of all other dimensions remain the same. For example, if A is a matrix, then sum A,2 is a column vector containing the sum of each row. For example, if A is a matrix, then sum A,[1 2] is the sum of all elements in Asince every element of a matrix is contained in the array slice defined by dimensions 1 and 2. To sum all elements in each page of Aspecify the dimensions in which to sum row and column using a vector dimension argument. Since both pages are a 4-by-3 matrix of ones, the sum of each page is If you slice A along the first dimension, you can sum the elements of the resulting 4 pages, which are each 3-by-2 matrices. Starting in Rb, to sum over all dimensions of an array, you can either specify each dimension in the vector dimension argument, or use the 'all' option. Create a 4-byby-3 array of ones and compute the sum along the third dimension. Create a vector of bit integers and compute the int32 sum of its elements by specifying the output type as native. Create a vector and compute its sum, excluding NaN values. If you do not specify 'omitnan'then sum A returns NaN. If A is a scalar, then sum A returns A. If A is an empty 0-by-0 matrix, then sum A returns 0. Data Types: single double int8 int16 int32 int64 uint8 uint16 uint32 uint64 logical char duration Complex Number Support: Yes. Dimension to operate along, specified as a positive integer scalar. If no value is specified, then the default is the first array dimension whose size does not equal 1. Dimension dim indicates the dimension whose length reduces to 1. The size S,dim is 1while the sizes of all other dimensions remain the same. Data Types: double single int8 int16 int32 int64 uint8 uint16 uint32 uint Vector of dimensions, specified as a vector of positive integers. Each element represents a dimension of the input array. The lengths of the output in the specified operating dimensions are 1, while the others remain the same. Consider a 2-byby-3 input array, A. Then sum A,[1 2] returns a 1-byby-3 array whose elements are the sums of each page of A. Output data type, specified as 'default''double'or 'native'. These options also specify the data type in which the operation is performed. This function fully supports tall arrays. For more information, see Tall Arrays. The outtype and nanflag options must be constant character vectors. If you specify dimthen it must be a constant. The order of the additions in the sum operation is not defined. The difference might be significant when A is a signed integer type and its product is accumulated natively. The order of the additions in sum operation is not defined. Therefore, the sum operation on a distributed array might not return exactly the same answer as the sum operation on the corresponding MATLAB numeric array. A modified version of this example exists on your system.
