problem on import excel file in Simulink

When i input an excel file in Simulink as a matrix, is a 1X8760 vector about wind speed data over the year, it doesn't recognize the min and max values. Hence, when i run my simulation i have a message error. The data in excel has a general format. If i try to input other excel files similar to the latter one (same excel format and same 1X8760 vector), it works. Can you help me? Thank you for the attention Best wishes

How are you bringing the data from Excel to Simulink? What blocks are you using in Simulink to represent your data? What is the exact error message that you are receiving?
