Comparing a number matrix to certain values and storing it in another array / matrix

Hello

To give a background on what im working on. I have a 20x20 matrix that consists of numbers between 1 and 5, i want to be able compare each number to a certain range so if the range was 1-2 i'd want all number between 1 and 2 inclusive to display a number 1. If the range was 3-4 i want all numbers that fall in the range to display a number 2 in another 20x20 matrix. In essence i want to display another matrix showing numbers that fall within each range and using a given display value for it,

Hey Wilhelm,

Because your ranges are from one integer to the next, you can accomplish your desired workflow using the "floor" command. Its documentation is below.

https://www.mathworks.com/help/matlab/ref/floor.html

Here is a brief example that creates a matrix with random numbers between 1 and 5, then uses the "floor" method to bin the numbers to the closest, smaller integer.

>> example = 1+(4*(rand(3)))

example =

      1.3034    4.1167    3.2753
      1.2158    4.7360    2.8776
      3.1232    1.5196    1.0476

 >> floor(example)

ans =

       1     4     3
       1     4     2
       3     1     1

R = 5*rand(4);
A = zeros(size(R));
A(R>=1 & R <= 2) = 1;

B = zeros(size(R));
B(R>=3 & R <= 4) = 2;
