how to have numerical or logical matrix or cell array

i got ann error allert: Error using newff>new_5p1 (line 153) Inputs are not a numerical or logical matrix or cell array.Inputs are not a numerical or logical matrix or cell array.

my input is vector of 24 x 500 double, in this vector included zero value,for example

   Columns 1 through 19

how to convert them into numerical or logical matrix or cell array ? and why my vector 24 x 500 double cannot passing as an input in neural network?

[Image Analyst]

A vector can't be 24 x 500, that's a matrix. Vectors are 1-D. What does this say in the command window?

really ? i saw dataset thyroid in nprtool has similiar value with my own input. i thought thyroidinputs and mydataset are same datatype. Ok, here is command window says :

Name      Size             Bytes  Class     Attributes

t         4x600            29392  double

so how to convert this matrix so i can use as input in neural network ? i have search any words related to convert numerical matric,logical , cell array in matlab , but still no result.

The nomenclature of vector vs array/matrix is a red herring here; IA is correct in the terminology but that's not the cause of the error.

We don't have enough information to answer the root cause of the error, we have the error message but in isolation, not including the calling code that preceded the error.

Cut and paste the entire sequence from the command issued till the next blank command line prompt in context without cutting/trimming anything...

i copied and past the entire command issued:

Error using newff>new_5p1 (line 153)
Inputs are not a numerical or logical matrix or cell array.

Error in newff>create_network (line 129)
  net = new_5p1(varargin{:});

Error in newff (line 101)
  out1 = create_network(varargin{:});

Error in trial4 (line 209)
net = newff(input,target,[75 40 24],{'logsig','logsig'},'trainlm');

any help, i really appreciate .

i changed my input become 4x600 and the target also. this is my code

 target = zeros(4,600);
target(:,1:25) = 1;
target(:,26:50) = 2;
target(:,51:75) = 3;
target(:,76:100) = 4;
target(:,101:125)=5;
target(:,126:150)=6;
target(:,151:175) = 7;
target(:,176:200) = 8;
target(:,201:225) = 9;
target(:,226:250) = 10;
target(:,251:275)=11;
target(:,276:300)=12;
target(:,301:325) = 13;
target(:,326:350) = 14;
target(:,351:375) = 15;
target(:,376:400) = 16;
target(:,401:425) = 17;
target(:,426:450) = 18;
target(:,451:425) = 19;
target(:,426:450) = 20;
target(:,451:475) = 21;
target(:,476:500) = 22;
target(:,501:525) =  23;
target(:,526:600) =   24;

Well, there doesn't seem to be a Matlab function newff, so we don't know what it needs for arguments.

So, what's lacking is the definition of the function from which can tell what the expected inputs are.

What does

help newff

tell you? Or, if newff is a hidden or local function inside the NN Toolbox, then need the input for the actual function called that, in turn, calls it and passes arguments thru via the varargin route shown.

Again, start with the code you executed first, and then the resulting error message and callback stack; as is we still only see the stack and not the initial code. Plus the information for the function(s) called that describes their expected arguments.

The message indicates you're calling with the wrong arguments; problem is we can't tell what the arguments are supposed to be from the selective snippets you've posted that aren't pertinent to the problem.

ADDENDUM

Specifically, start with a clean command line prompt in view; type in the command(s) that generate the error and then paste the complete session to the next prompt intact...

>> help newff

 newff Create a feed-forward backpropagation network.

   Obsoleted in R2010b NNET 7.0.  Last used in R2010a NNET 6.0.4.

   The recommended function is feedforwardnet.

Hope this helps.

Ah! I haven't ever had NN TB and newff doesn't show up at all in the current online doc...
