why do i get an error in my code?

load("stormData"); 
stormData.Property_Cost(ismissing(stormData.Property_Cost))=0; 
stormData.Crop_Cost(ismissing(stormData.Crop_Cost))=0; 
stormData.Total_Cost(ismissing(stormData.Total_Cost))=0;
summaryRegionCosts= groupsummary(stormData, "Region", ["min", "median", "mean", "max"], "Total_Cost")
stormDataPos= stormData(stormData.Total_Cost > 0, :)
summaryRegionPosCosts= groupsummary(stormDataPos, ["min", "median", "mean", "max"], "Total_Cost")

TT = load("stormData");

Load the data into variable nd use it in groupsummary

summaryRegionCosts= groupsummary(TT, "Region", ["min", "median", "mean", "max"], "Total_Cost")

[Emem]

load("stormData"); 
stormData.Property_Cost(ismissing(stormData.Property_Cost))=0; 
stormData.Crop_Cost(ismissing(stormData.Crop_Cost))=0; 
stormData.Total_Cost(ismissing(stormData.Total_Cost))=0;
summaryRegionCosts= groupsummary(stormData, "Region", ["min", "median", "mean", "max"], "Total_Cost")
stormDataPos= stormData(stormData.Total_Cost > 0, :)
idx= find(stormData.Total_Cost > 0)
postVals= stormData.Total_Cost (idx)
summaryRegionPosCosts= groupsummary(postVals, "Region", ["min", "median", "mean", "max"], "Total_Cost")
%% a new code i wrote but it is still generating an error message

[VBBV]

if you load the data, do you view it as table array or numeric array ?

load("stormData"); 

groupsummary takes table or timetable data only as input source

[Emem]

I view it as a table error and attached is the error message i keep getting.

[Emem]

Unfortunately, i am unable to load the data into variable and use it in groupsummary.

load("stormData"); is uneditable in Mathworks external tool.

• before all of this your MATLAB path might be very messed up
• you might have a variable named "path" in your mat file that is messing everything up (but the message would be different for this case I think)
• most likely case: either before this you assign to a variable named "find" or else you are loading a variable named "find". The error message is completely compatible with the possibility that you have a variable named "find" stored in the file.
