How to assign a variable based on an equation?

I need to update certain material properties as a system cools. The properties are dependant on temperature, and I have equations that relate the values of the properties to temperature.

Is there a way to store an equation of a single variable, then use that equation to determine the value for a new variable?

I want to be able to define the equation at the start of the code and use that equation to determine the new property.

Something along the lines of:

Density_equation = x^2 + 2x + 10

T = 1000

Density = Density_equation(T)

I hope this makes sense, I am having trouble articulating my question.

[Paul Hoffrichter]

Inline anonymous functions can be defined as follows:

Density_equation = @(x) x^2 + 2*x + 10

Density_equation = function_handle with value:
    @(x)x^2+2*x+10

T = 1000

T = 1000

Density = Density_equation(T)

Density = 1002010
