i wrote code for svmtrain code is alpha=svmtrain(x,y) get output for this

alpha =

          SupportVectors: [7x1 double]
                   Alpha: [7x1 double]
                    Bias: 0.0194
          KernelFunction: @linear_kernel
      KernelFunctionArgs: {}
              GroupNames: [10x1 double]
    SupportVectorIndices: [7x1 double]
               ScaleData: [1x1 struct]
           FigureHandles: []
 here, the result shows correctly for svmtrain,when i cal for this svmclassifier i,e..
 alpha=svmclassify(alpha,test)
it show error...
??? Attempted to access svmStruct.ScaleData.scaleFactor(2); index out of bounds because numel(svmStruct.ScaleData.scaleFactor)=1.
