For a thermistor, a temperature sensitive resistor, the relationship between temperature, T$,$ and Resistance, R should conform to this equation:

Determine the constants c$1$ and c$2$ using MATLAB's nlinfit and experimental R and T data:

R T

$983\mathrm{.}8318$

$811\mathrm{.}3323$

$469\mathrm{.}0338$

$240\mathrm{.}9358$

$87\mathrm{.}7393$

$77\mathrm{.}0398$

$53\mathrm{.}0413$

$41\mathrm{.}9423$

Use a guess value of $0\mathrm{.}01$ for all unknowns

ln is the natural logarithm
