How to divide in matlab

Complex Conjugate Transpose. The complex conjugate transpose of a matrix interchanges the row and column index for each element, reflecting the elements across the main diagonal. The operation also negates the imaginary part of any complex numbers. For example, if B = A' and A (1,2) is 1+1i , then the element B (2,1) is 1-1i.

This MATLAB function splits str at whitespace into C. Delimiting characters, specified as a character vector, a 1-by-n cell array of character vectors, or a 1-by-n string array. Text specified in delimiter does not appear in the output C.. Specify multiple delimiters in a cell array or a string array.Divide Inputs of Different Dimensions Using the Divide Block. This example shows how to perform element-wise (.*) division of two inputs using the Divide block. In this example, the Divide block divides two scalars, a vector by a scalar, a scalar by a vector, and two matrices.Aug 30, 2014 · Perfect setup for bsxfun with @rdivide option to let v internally expand to the size of M and then perform elementwise division - d = bsxfun(@rdivide,M,v) Benchmarking on solutions The better approach though would be to remove the for loop and generate a logical matrix the size of R that is true when that number is divisible by 12 and false otherwise by passing the entire matrix to rem. is_divisible_by_12 = rem (R, 12) == 0; Then we can use this to compute the sum of these by using this logical array as an index into R.May 1, 2019 · Select a Web Site.
