set zero in matrix elements MATLAB Answers - MATLAB Central
A very straightforward way to do this is to use a for loop. It might not be the most efficient approach in MATLAB, but it's probably good enough considering your data set is so small.... Every variable in MATLAB® is an array that can hold many numbers. When you want to access selected elements of an array, use indexing. When you want to access selected elements of …

All combinations of two elements from a 3 by 7 matrix

The simple answer is to take all possible combinations of 2 elements (without replacement) from the entire array, then toss all cases where the elements came from the same column. This extends simply (in theory) to combinations or more elements. I'd call this a rejection scheme, where you start with the set of all possibilities, then toss those that fail your constraint....
Matrices have to remain rectangular. What would you want the answer to be if you deleted elements greater than 8 so just the 2 9's get removed?

  • MATLAB's real power comes into play when more than a single element of a matrix is wanted. To indicate "all the rows" use a colon for the first expression. To indicate "all the columns", use a colon for the second expression. Thus, with:
  • I have a function who's output is a 1 dimensional array of random numbers i.e. rows = [1 2 5 19], how do I call those corresponding rows from a matrix i.e.
  • Then, I want the output of the code to be written to a new 2d array in the correct element location. So after the (1,1) elements are run through the code, the 'answer' of the code will be written to the new array in location (1,1). However, I am not sure how this for loop should be written, or how to call on the particular location that the for loop is being run on so that the output can be
  • Minimum elements from A or B, returned as a scalar, vector, matrix, or multidimensional array. The size of C is determined by implicit expansion of the dimensions of A and B . For more information, see Compatible Array Sizes for Basic Operations .
