reduce cell size of bivariante diagram

Hello,

I want to reduce the size of cell in a bivariante digram.

Someone told me that maybe with some interpolaton and curve fitting the could be improved.

I have tried to apply interp2 but the result was bad.

I copy the script.

BC= [ 0 0 0.149 0.524 0.717 0.268 0.275 0.340 0.330 0.943 0.623;

0 0 0.402 5.518 9.337 4.833 1.370 2.233 2.675 6.665 6.960;

0 0 0 0.710 6.047 6.910 1.925 1.117 1.186 3.558 7.161;

0 0 0 0 1.040 3.759 3.451 0.662 0.558 1.352 3.471;

0 0 0 0 0.042 0.985 2.449 0.700 0.325 0.618 1.732;

0 0 0 0 0 0.146 0.978 0.787 0.166 0.380 1.059;

0 0 0 0 0 0.015 0.179 0.427 0.164 0.228 0.516;

0 0 0 0 0 0 0.007 0.127 0.084 0.094 0.233;

0 0 0 0 0 0 0 0.032 0.052 0.084 0.089;

0 0 0 0 0 0 0 0.017 0.032 0.030 0.055;

0 0 0 0 0 0 0 0 0.007 0.040 0.052];

imagesc(BC)

How can draw smaller square?

Thank you in advance.

Best regards,

María
