Change of Ratio of train and test and val in Neural network

Hi everyone, I have a question please: I want to change the ratio of train, test, and validation by:

net.divideparam.trainRatio= 60/100;
net.divideparam.valRatio= 20/100;
net.divideparam.testRatio= 20/100;

but when in workplace I type tr and enter, I get:

         trainInd: [1×70 double]
         valInd: [4 16 17 35 41 49 51 63 66 69 75 79 85 98 99]
         testInd: [5 8 12 13 29 33 34 40 45 50 53 62 72 80 97]

this means that these didn't change, isn't it?
