WebJun 11, 2024 · Calling the Elements of a Vector in Matlab. If you create a vector in Matlab, you can call the separate elements of that vector. You can use these separate elements in different calculations. t(3) = 4.0. For example, we created a vector with an incremental value. If we need to call the third value of that vector, we can write t(3). WebSuppose I have an NxN matrix A, an index vector V consisting of a subset of the numbers 1:N, and a value K, and I want to do this: for i = V A(i,i) = K end Is there a way to do this in one statement w/ vectorization? e.g. A(something) = K. The statement A(V,V) = K will not work, it assigns off-diagonal elements, and this is not what I want. e.g.: bittrex staking cardano

WebThe relational operators perform element-wise comparisons between two arrays. The arrays must have compatible sizes to facilitate the operation. Arrays with compatible sizes are implicitly expanded to be the same size during execution of the calculation. In the simplest cases, the two operands are arrays of the same size, or one is a scalar.
