How to create a matrix using two arrays (x & y) and a formula that uses x & y

6 views (last 30 days)
So if
x = [4.0:-.05:3.7]
&
y = [9;15;21;27;33;39;45]
&
z = 1.3473*152/(152+y)+(5-x)*y/(152+y)
How do I create a matrix that calculates output z at the different possible combinations of x & y?

Use implict expansion.
x = [4.0:-.05:3.7] ;
y = [9;15;21;27;33;39;45];
z = 1.3473*152./(152+y)+(5-x).*y./(152+y)
z = 7×7
1.3279 1.3307 1.3335 1.3363 1.3391 1.3419 1.3447 1.3161 1.3206 1.3251 1.3296 1.3341 1.3386 1.3431 1.3051 1.3112 1.3173 1.3234 1.3294 1.3355 1.3416 1.2949 1.3025 1.3100 1.3175 1.3251 1.3326 1.3402 1.2853 1.2943 1.3032 1.3121 1.3210 1.3299 1.3389 1.2764 1.2866 1.2968 1.3070 1.3172 1.3274 1.3376 1.2680 1.2794 1.2908 1.3022 1.3137 1.3251 1.3365

Use the meshgrid function to create 2-dimensional grids from the x and y vectors. The first example in the documentation is very similar to what you want to do.
