Hi. I want to know how can i reduce these if statements with two conditions.

I have tried following code but it is very lengthy to use for like 50 values.

X = {'1';'2A';'2B';'3';'4'}';                          %Seismic Zone
Z = [0.075, 0.15, 0.2, 0.3, 0.4]';              %Zone factor
zTbl = table(Z,'RowNames',X);              %Table of Zone and Zone Factor
x = input('What is seismic zone?: ','s');  %Seismic Zone input
Z = zTbl{upper(x),'Z'}                             % Z factor assigned
SP=input('What is SP?: ','s')
SP1=upper(SP)
if Z==0.075 & SP1=='SA'
    Ca=0.06
elseif Z==0.075 & SP1=='SB'
    Ca=0.08
elseif Z==0.15 & SP1=='SA'
    Ca=0.16
.
.
end

Create an array with all implemented values of CA. Then you can use array operations to find the index, which will allow you to easily add cases and detect combinations that aren't implemented.

Like this?

CD1=input('What is closet distance to known source?:');
if CD1<CD(1),CD1=CD(1);elseif CD1>CD(end),CD1=CD(end);end
