MATLAB: How can i obtain this

matrixmatrix manipulation

i would like to use the command reshape to convert a vector v=11:99 to a matrix (9×9), how can i do this, can anyone help me ?

Best Answer

You can not do it when v=11:99.

If you want to convert to 9x9 matrix, then you need to have 81 elements in your vector, with this you have 89. If you define it as v=11:91, then the following command will do what you want.

v=reshape(v,9,9)

I suggest http://www.mathworks.com/help/matlab/ref/spline.html

x = 1 : length(psdn);
x128 = linspace(x(1), x(end), 128);
p128 = spline(x, psdn, x128);
plot(x128, p128);

something like this maybe,

a = [81 83 85 87 90
  84 0  88 90 92
  83 85 86 0  91
  86 87 88 92 94
  88 89 90 96 99];
 a = a(:);
 x = 1:numel(a);
 xq = find(a==0);
 x(a==0)=[];
 a(a==0)=[];
 interp1(x,a,xq)
ans =
     84
     91
