Hi Friends,

          I am having one  Matrix X of order mxn. I need to perform this operation.

Variable Y=  X- (Mean of X) .

The mean of Matrix is a column matrix. how to solve this equation.  The matrix size can vary dynamically.. how to solve this equation. Please help me out

Hi deepak.aamecece,

you can use the MEAN.vi. It works with arrays.

hi deepak,

  I could not understand your question?Why are you trying to substract a matrix from a column vector(mean)?

Thanks and regards,

Mathematically speaking, you cannot subtract a column matrix from a "rectangle" matrix. You may add or subtract only with equal size matrices.

What do you mean with X- (Mean of X)?

Hi...

Let X is a matrix of size  4x4. The mean of (X) is a Column matrix. I know it is not possible in mathematics... but I need to subtract this for the application need... How to do this?

hi deepak,

  Only thing you can do is you can reshape the column matrix to a 4x4  and perform the operation you want..

Thanks and regards,

 Hi Friends.. I solved like this... Please find the attached jpg file....What i did is: matrix X is 4x4 matrix. Mean of Matrix X is a Column matrix. I separated the first column of a matrix X. I subtracted from Column matrix and i appended back the result to the original matrix..

Thank you one and all for your effort you had taken to help me in this regard.
