Substitute Expressions in Matlab
This function provides a supplement to the Matlab Symbolic toolbox to substitute and simplify long expressions. Maple does not provide this functionality.
input-- Input expression that has some terms to be substituted.
>> input='a^2-2b+c-3';
>> inputmode=1;
Note that 'inputmode=1' indicates that the input is a
string expression;
subexp-- If ‘subexp’ can be found inside 'input' expression, then all the instances of ‘subexp’ are substituted with the expression 'var'
outputmode-- output is a character string if ‘outputmode=1’;
Note: Read help for the other options.
EXAMPLE:
input='a^2-2*b+c-3';
subexp='c+a^2';
var='Z'
inputmode=1;
outputmode=1;
out=SubsExp(input,subexp,var,inputmode,outputmode);
ANSWER
>>out =Z - 2*b - 3
