  please check the input matrix you have defined and the output oubtained. I have encountered this error, generally when I do multiplication and end up having more rows or columns that what i defined earlier.

  hey. Thanks for replying. But i have 1*37(1 row 37 columns in 1 matrix) and 2*37(2 rows 37 columns in another matrix.) I am not multiplying these matrices. But giving the inputs (2*37 matrix) and targets (1*37 matrix) to the neural networks (feedforward). And train the system. and just while testing this network when I give the inputs, i get this error. Can you please help me in MATLAB neural networks? I am a newbie to MATLAB and finding it really tough.

  ok.. I am not familiar with neural network toolbox, but as I understand you are trying to feed in weekday and time of the weekday as cpinputs and the winning number as cptarget. what you might have not done is doing a transpose as mentioned by the author(step 9). I religiously followed the steps provided by the author and could arrive to the desired outcome.

  I followed all the steps they have mentioned. i did the transpose even. But i am getting that error. I am using MATLAB 7. Do we need to do any initial settings or something?? I dont know how to proceed. And thanks a lot for replying.

  Also, as given in steps 6,7 and 8, in MATLAB 7 on clicking File menu I get Import Data wizard wherein I imported the .xls file. Finally got a variable generated in MATLAB (this contains the entire 3*3 matrix). Next, to select the 2 columns I double clicked on the variable generated in workspace. On selecting the 2 columns->right click-> select 'create variable from selection'. This generates another variable with the 2 columns that I renamed as cpInputs in MATLAB workspace. The same is done for cpTargets. Is this method right? Cause, otherwise as given in those 3 steps i dont get how to select the 2 columns and then hit Import button. There is no such option given.

  I am using matlab 2008, i had little issue selcting columns as well, but this is how I have done, I moved the column from B and pasted in C and copied column C in B, now I had data from B(weekdays) and time (D) next to each other and selected. The target number was now in column B instead of C.
  I am atatching a doc for your assistance,

  hey... Even I copy pasted the two columns for selecting them together. And thanks for the screenshots. I followed the same procedure, but get those errors. Have any idea how to proceed? This is related to my final year project. I am stuck. I cannot proceed without solving these errors. 😔
