v1 = randi([1 6],1,10) % Example data
v1 = 1x10
4 6 5 2 4 1 1 2 1 1
<mw-icon class=""></mw-icon>
<mw-icon class=""></mw-icon>
% Replace any value less than 4 with 0
v1(v1 < 4) = 0
v1 = 1x10
4 6 5 0 4 0 0 0 0 0

We use "vector indexing" to achieve this.
When you apply a "condition" on an array, the result will be a logical array where, the corresponding indices in the result will be a 1 or a 0. You can use the result array to apply it back on v1 and modify the values where the "logic" holds true. You can use this to compare an array to a value, or even two equal sized arrays and their corresponding index values! You can find more on this using the following link:
