To find the rows of data that have the same minimum and maximum values, and remove the rows.

I need to remove the rows that have same minimum and maximum values , below is the code used .

but it gives error:

Unable to perform assignment because brace indexing is not supported for variables of this type.

Kindly help

m = min([XTrain{:}],[],2);
M = max([XTrain{:}],[],2);
idxConstant = M == m;

for i = 1:numel(XTrain)
    XTrain{i}(idxConstant,:) = [];
end

Please give complete info so that anyone can replicate your snippet. Here what is XTrain?

Sorry fo rthe inconvenience.

XTrain is a 576*5 double numerical array

[Ive J]

So, why are you treating it as being a cell array?

XTrain = rand(576, 5);
m = min(XTrain,[],2);

Thank you for the reply.I tried to load data using read table and still brace indexing error is getting for the for loop.

"Unable to perform assignment because brace indexing is not supported for variables of this type."

Please post a sample piece of your data you are trying to load using readtable.

You just mentioned your XTrain variable is double (maybe readmatrix is what you want?)

Also please check

class(XTrain) % should be double in your case, otherwise it's not double

Kindly see the attached XTrain

[Ive J]

XTrain = readmatrix('XTRAIN.xlsx'); % read as matrix not table

[NN]

thank you , i will check this

if XTrain is an array, then

XTrain{i}

is both meaningless and causing the error. Use

XTrain(idxConstant,:) = [];
