Store the structure fields generated in a for loop into a vector

Hello everyone, I have a small problem here, my 1*2 struct of the name 'ord' has 7 fields as can be seen in the figure.

This structure is generated in a 'for' loop. So, depending on the looping condition it can also be a 1*3... 1*n struct. I am required to create a vector which contains the field data of 'rpm' which gets generated each time the 'for' loop runs. In other words, I simply want to store ord(1).rpm, ord(2).rpm and so on.. into vectors. In this case it is just a 1*2 struct, I am looking for a code which can store the data generated in the rpm field as and when it gets generated while in loop!

Thank you in advance!

Use a cell array:

 RPM{i} = ord.rpm;

Rather than doing this one element-at-a-time and extending the cell array, the most efficient answer is to get all of the values into one cell array like this:

{ord.rpm}
