在 MATLAB Online 中打开

Something like this?

Name={'a','a','a','b','b','c','a','a'}.'
Value=randi([1 7],size(Name,1),1)
Tab=table(Name,Value)
A=Tab.Value(strcmp(Tab.Name,'a'))

You generate 8 values for Value array randomly, then you gather them in a table. After that, you check which rows contains name a and by the power of logical indexing, you extract the values in those rows and store them in a new array.
