What's worng with this code

Error:

Index at location 2 exceeds array boundaries, index must not exceed 10.

Data seems to be a function and a variable at the same time. If this is not intended, use 'clear data' to remove the variable 'data' from the workspace.

Korean currency combination.xlsx = 한화 합본.xlsx

Incorrect number or types of inputs or outputs for function estimate.

disp(var_model);

estimate() requires that a model be passed. To create a VAR model you would use something similar to LagOp

In addition to what Walter has mentioned,

> Use the more robust readtable (or readmatrix) instead of the depracated xlsread().

>The variable names don't match -

DivideYield = data(:, 2);
Y = DividendYield;

> The first column is the date-time data, not E_Price. There is a mismatch for other variables as well. And there is no data column named KOFR in the excel file
