Showing different value in image with different color in Matlab -

-

i working in matlab 2009. have array (say test) like:

 0    0    0     0  1.2 1.2  1.4  1.6  1.2 1.3  1.3  1.7

this array represents image after performing few operations.

i want same values represented in 1 color. pixels corresponding value 1.2 should represented in red color (while using imshow function).

how can done? please help

the function imagesc assign 1 color per value.

the code

a=[ 0    0    0     0      1.2 1.2  1.4  1.6     1.2 1.3  1.3  1.7];  imagesc(a);

will produce

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
