How do I name individual cells from a cell

I'm creating a .mat file with some parameters (angle = array and transmission = cell 1x9 with 12000x20 individual cells). How do I name and save each 12000x20 cell with the name "generic" + individual component of the array "angle". Note that cells in "transmission" were calculated based off the order of angle, so order should already be matched up. Necessary for calculations based off another function.

What does "cell 1x9 with 12000x20 individual cells" exactly mean? The expression "save each 12000x20 cell with the name "generic" + individual component of the array angle" is not clear also. I do not understand this also: "Necessary for calculations based off another function."

There are nine 12000x20 cells in the transmission cell; therefore, "transmission" is a 1x9 cell.

I need a generic name for each of those 12000x20 cells where the names ends with the value of a component of "angle"

"How do I name and save each 12000x20 cell with the name "generic" + individual component of the array "angle""

Don't do this. Using indexing is much simpler, most efficient, and easier to debug.

"Note that cells in "transmission" were calculated based off the order of angle, so order should already be matched up"

That is exactly what indexing does: keeps things in a particular order. So easy with indexing!

Thank you, I'll look into indexing.

A bold guess: You want to use a struct?

Note that creating 12000x20 different variables or fields of a struct would be extremely inefficient and very ugly. You would have to hide an index in the names of the fields, and this is a bad idea. See Tutorial: Avoid the dynamic creation of variables.

[fernando aguirre]

You are correct! I need a struct the holds the same number of values that angle has in components which in this case 9 (updating question because I forgot that angle was a 1x9 array). It does seem messy, but it's my only choice until I find another method of preselecting files for a function that it i.e. "Necessary for calculations based off another function."

I assume, that using an array is much more efficient and cleaner, than a huge struct with magically numbered field names. I simply refuse to post code to produce 240'000 field names, although this is very easy using sprintf and "dynamic fieldnames" (use these terms to search in the forum). I'm too convinced, that this method will be a shot in your knee and I'm not willing to hut you.

I suggest to explain the actual problem with more details to get a better strategy than a huge struct array. Currently the explanations of what you want to do are not clear enough to be understood.

It's really only 20 field names, but fair enough. Thank you for your help!
