Using a statement to identify a specific matrix with a given range of values.

I am hoping to get some help with a question concerning using a value range in MatLab. I am trying to write a statement where if the value of a variable falls within a given range, than a specific table of values is selected.

I am using the following code to round values for atmosT and RH:

 roud_atmosT = round(atmosT);
 roud_RH = round(RH);

and have the following selection of matrices: x15C_ab, x17_5C_ab, x20C_ab, x22_5C_ab, x23C_ab

so for example, "if the value for roud_atmosT is 15 to 17, than ambient_T = 'x15C_ab'

Let me know if you need any more info or further explanation/definition. Thanks for any help you can give.

Hi,

for what I understand, you need something like

if roud_atmosT>=15 || roud_atmosT<=17
    matrix_name = sprintf('x%dC_ab',roud_atmosT);
    ambient_T   = eval(matrix_name);
end

and then add some else if cases for all your values.
