Simulink does not support loading the input data in file

I have a 1x1000 matrix named inputsignal.mat. It is saved in version 7.3.

I am trying to view the signal using a scope on Simulink:

I am getting an error: Simulink does not support loading the input data in file. Simulink can only load two-dimensional arrays or timeseries objects. The array must consist of one-dimensional, double, noncomplex samples. To load data having a different type, complexity, or dimension, use a timeseries object. For either an array or a timeseries object, at least one sample point is necessary.

My data is as follows, with a value of 1x1000 double

What do I need to do such that I am able to load such data type? Any help would be appreciated.
