Table Multiplication error: Both tables must have the same variables
154 ビュー (過去 30 日間)
I am trying to figure out why these table columns will not multiply together. It is a table of one size of imaginary numbers 94x3
Var1 Var2 Var3
_________ _________ _________
0-10059i 0-5021.2i 0-3338.1i
0-8800.5i 0-4390.5i 0-2916.2i
0-7821.1i 0-3899.7i 0-2587.6i
0-7037.5i 0-3506.6i 0-2324.3i
0-6396.2i 0-3184.7i 0-2108.3i
I am getting an error when doing SAI(:,1) .*SAI(:,2).
It gives the same error when using *
Error using .*
Both tables must have the same variables.
What am I doing wrong here?
Thanks for any help

One simple solution is to use curly braces to access table content (not parentheses which return another table):
% ^ ^ ^ ^
How to access table content is explained in the documentation:
Most likely using numeric arrays would be even better, as Dyuman Joshi suggested.
"What am I doing wrong here?"
Parentheses returns a table. Your parenthesis indexing returns two tables, each of which has exactly one column/variable. But the names of those variables are different. But tables can only be operands to an operation if they have exactly the same variable names, as the documentation makes clear:
Because your two tables have different variable/column names your code throws an error.
Solution: don't try to multiply tables with different variable names.
