How to evaluate an equation with multiple points for a variable.
显示 更早的评论
I have RE = V*D/NU and another equation C = 3.*RHOBAR/(4.*D) both variables RE and C appear in other equations, which will eventually end up in a plot. I want set multiple values for D. How do I solve this?
If I use D=[.1 .05 .001] I get an error stating Matrix Dimensions must agree

Make sure you have placed dot before operators for vector variables in your reynolds number RE, C and in equation containing RE and C.
In general,
* % matrix multiply
.* %scalar multiply
/ % matrix divide
./ % scalar divide
^ % exponentiation
.^ % element-by-element exponentiation
